FAQs for booking flights from Sydney to Boston

  • Is there an airport lounge I can use at Sydney Airport while I wait to board my flight?

    Yes; whichever terminal you're flying from, there will be an airport lounge within easy walking distance of your gate at Sydney Airport. It has around a dozen lounges spread across all of its passenger terminals, clustered mostly in terminal 1 (the airport's busiest terminal). Some of these lounges are airline lounges, which you may be able to access with your ticket depending on which airline and ticket class you choose, and some are pay-per-access. Tickets to Sydney Airport's Plaza Premium Lounge start at around A$ 40 per person for a 3h slot. You'll be able to enjoy premium food, a wide variety of free beer, liquor, wine, and non-alcoholic beverages, and more tranquil conditions than the busy terminal.

  • How should I travel to central Boston from Boston Airport?

    There's a free shuttle bus called the Silver Line Bus (SL1), which will take you from your terminal to South Station in central Boston. The journey takes around 25-30min, and from there you can easily transfer wherever you need to go in Boston, as South Station has a metro stop on the red line, which connects to all of Boston's other subway lines. If you have a lot of luggage or would just rather be dropped off at your door, you can get a taxi; it'll cost about $25-30 (A$ 33-38) and should take under 20min, depending on traffic conditions. You can get the shuttle bus or catch a taxi from bus stops and taxi ranks directly outside every terminal.

There were no food or entertainment on this short flight. Friendly staff even before getting on the flight. The seats were snug but it was quick flight

Good flight. On time. No problems. Plane was clean. Service was as you would expect. However nothing special, just a good flight.

Very friendly staff. No food service and no entertainment. Only 1hr 20min flight

High fees for excess checked baggage and somehow ridiculous rules for carry on bags.

Flight was late, food and drink an extra charge, my carry on is five rows behind me, and the seats are too narrow. Don’t ask me to be happy about it

I bought flights in August and there wasn’t a flight in the system

Our 6.30am flight was boarded then cancelled to fly at 10.55am . We were flying to Brisbane to attend a funeral at 12 noon an hour away . This means missing the funeral due to unreliability of Virgin . Unimpressed !!

It was with Link Airways and the Saab 340 jet was noisy and little comfort.

They didn’t sent my luggage I got it 24 hours later

Plane was late and they wouldn’t check our bags through to Tokyo

We had a cancellation due to weather, but the American Airlines staff was very helpful. Once we got on a plane, the trip was great.

Great food and good entertainment options for the long flight.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

On the Qantas flight, I could barely hear some of the announcements. It was better when I could read them on the screen.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

Our boarding and flight was very good. However when we landed and pulled in to the gate it took 55 minutes for the jet bridge to be positioned next to the aircraft. That caused us to miss our ground transportation and it caused us unnecessary last minute transit planning and expense. Our flight was AA1733 on March 17, 2026

We booked with Qantas instead of Delta and we instead flew on American Airlines. American is not our favorite to go on. No leg room and the width of seats are a joke. Your are packed like sardines on American flights.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Broken tray table. Erratic service. Premium economy is more economy than premium- other airlines treat PE much better. No lounge access.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

We had a delay, but thankfully I made it to my connection. Overall it went smooth

The flight had a delay but I made it to my connection. Flight was smooth overall

As I wrote earlier, poor planning and/or communication. At least twice, we were told that we would be boarding in less than ten minutes, only to have the flight again delayed at least another hour.

Our flight from Nice to Newark ran an hour late, and the food was mediocre, but it was fine. The problem was that we were scheduled to have a 4.5-hour layover in Newark, but then our flight to RDU was almost four hours late, finally departing at almost 11:30 p.m. We understand that flight delays were caused by weather problems in the East. However, there were at least two times, when were told that we would begin boarding in just a few minutes, only to have the flight delayed another 1.0-1.5 hours. This meant that we would leave a restaurant or the United Club, go to the gate, only to learn that there would be another major delay. Poor planning and/or communication.

This flight is a quick way to get to Chicago, but a bit expensive.

There were no facilities in the middle of the aircraft and premium economy was not allowed to use the business class facilities, and had to share the only two toilets at the back with economy. The upgrade to Premium was definitely not worth it

Flight left on time. Captain provided relevant announcements. We had to wait 45 minutes to desembark due to the ramp closed because of lightening.

The homeless eat better than what was served on that plane. Pretzels and ice cream? My last trip to Europe. Everything is small, but the bill.

Cancelled flight. Still waiting to get home for grand daughter’s graduation .

So overall the flight was just average and nothing special. They overbooked some of the flights and they ended up running out of overhead storage space so we had to check our carry-ons which wasn't terrible but we were inconvenienced because of the second connecting flight with a long layover we couldn't get our bags until the final destination. Most of the flight attendants were pretty good and overall the meals were not that great because the chicken was dry and overcooked. They also didn't provide butter or any kind of spread with the bread which is cheap and concerning. The American airlines staff at the check-in counter was kind of unprofessional because this lady just started singing in the middle of checking us in and that's weird. The worst part of the flights was the terrible conditions of the bathrooms which were unclean and did not have toilet paper or toilet tissue available which is kind of insane for a 14-hour and 8 and 1/2 hour flight.

The seat when "flat" was not flat and pad was too thin to cover it.

Awful customer service, horrible experience. We travel a lot domestic & international- worst flights to/from ever. Brief bkgd as Inhate to relive this experience: booked and chose 2 seats 4 months prior in Premium Economy - last row end seats close to bathroom, no one behind us, plenty of legroom;, underwear storage — flown this was on other airlines, love it. We receive notice 4 days before scheduled overseas flight - plane has changed, new seats assigned. Seats are split into single seats, opposites of the plane, FRONT Row so no reachable storage. Called BOTH British Air & America. American “switched planes and the seats you want are taken;” British Air “Yes, we’ll be glad to accommodate you (type type type). Just ask at the Gate and someone will give you new boarding passes with seats together in middle, OK?” — OK. —At Gate the attendant looks us up saying “No, it is an overbooked flight and yours are the only seats available.” But but but wait, “We were TOLD our seats had been switched and seated together?” Gate attendant “Well they were wrong and don’t change your seats. Your original seats are where you’ll sit.”. Right. No help WHATSOEVER. We sit opposite on way there, wife VERY disgruntled, a Tol 5 worst ways to start a 3-week bus tour of UK. We promise to NEVER FLY AMERICAN OR BROTISH AIR EVER, and we have 3 more extensive trips planned..

Requested early boarding to disinfect seat, tray table, etc. before general boarding. Instructed to board after wheelchair passengers. Waited on jet bridge behind 12 wheelchair passengers. Stopped immediately after entering plane to wait for gate agent in rear of plane cleaning a seat that was wet, got to my row and found both seats adjacent to mine already occupied, with the lack of room making it impossible for me to clean my own space and defeating the purpose of my boarding early. Cleaned the armrests and tray table as best I could.

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

The wifi experience is awful. I had to try again and again, taking over 30 minutes, to connect to the wifi. I had to watch the same two ads over and over until I was finally successful. Once connected, it was anything but "high speed" and disconnected at least three times during the flight.

Fine. Nothing to write home about. The plane left on time, and arrived on time.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

Never flown with Air Canada before, but it's now a top choice! Loved it!

Horrible crew, horrible seats configuration, ridiculous space in the toilets, Air Canada is no longer a option.

Crew at gate and onboard were just very OK, not very friendly and honestly seemed bothered to be there. I will give a shout out to still selling headphones for those who forgot.

Flight Boarded and departed on time. The Flight crew was very friendly and accommodating. The aircraft was clean and free from clutter and debris. I will be happy to recommend Air Canada to my friends and relatives for their flight needs. They were very attentive and responsive to our needs as Senior citizens.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

Flight operated by PAL. We boarded, and one engine started. The crew found some problem that could not be fixed. The flight was canceled. This run from yhz-bos is very unreliable.

Everything. The crew was so friendly, helpful & smiled. We had an excellent flight getting in earlier.

Flight itself was not bad at all. However: my checked bag (checked in Calgary) did not make it onto this flight as I found out after I landed at EWR. I still don't have it but it appears that it is on its way to me.

Flight and attendance were very good we had 2 hour delay that took the shine of it
