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.

Flight cancelled due to broken seat. $8 refreshment voucher barely bought a coffee. 3 hours to next flight. Also then delayed.

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

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.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

I missed my flight and had to buy new tickets Rome- Boston

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

Referencing ANA'S service to Japan and the return on UA, the pillow was awful, the crew was not very attentive, and the food was bizarre and tasted okay. Whoever's idea it was to make vegetable tempera in a steam capsule should probably revisit that. Since it was the vegetarian option, it was my only choice.

Crew was great! Good meals. Had room to stretch out

Our flight was delayed 2.5 hours from Lisbon to DC so we missed our connection to Seattle that would have arrived at about 9 PM. The agent initially said we had to stay overnight in DC and there were no other options to put us on to get us to Seattle. While on board I discovered a flight via American he could have put us in but by the time we arrived in DC that was sold out. We were then put on a flight to San Francisco that was also delayed then arrived in San Francisco and our flight to Seattle was also delayed so we ended up not arriving until 2:15 am. Our son could not pick us up so we ended up having to pay over $100 to Uber home. This is the second trip with United that the flight has been delayed causing us to miss an evening in Las Vegas and we were given nothing.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

My table was broken so it made it difficult to eat the food during the service. I was also informed that my luggage did not make it with me to Phoenix. I live two hours away so this makes it even more stressful to try and arrange a time for pick up

The Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

Another uncoordinated American experience. Always surprises me at DFW for them of all places. Have to take this flight as there are no other good time options. We knew from the start that something was wrong, but the pilot wouldn't tell us. I just watched my Kayak app grow the delay by 10 minutes as it went to 3.5 hours. They were uncoordinated with maintenance (as maintenance, when finally arriving, knew within 15 minutes the plane wasn't going. No 'sorry' or 'this is what is going on' comment. The pilot seemed unfazed / didn't care about the process we were going through.

The seats. The seat in front of me was awful and when the guy sat down, it flew back and hit my head when I was putting my backpack under the seat, It didn't make for a pleasant experience,

I’ve got 31F seat and window seat . My 2 co passengers was AA crew members and they were very rude attitude and when I was going to use bathroom their gestures was very different and awkward and the guy beside me completely occupied the hand rest and I was really uncomfortable

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

The middles seats on the 777 airplane are very small. I am only five feet tall and my knees were touching the seat in front of me and the is no leg room if you have a person item under the seat. The food was horrible, spicy sauces, tasteless bread, and wilted/brown lettuce. Keep it simple. The staff was mediocre., one minute loud and chastising, and the other friendly. We liked how clear and easy to understand the entry process in to the US was.

It was so much better than expected, Ohare is not such a pleasant experience but American Airlines with the new, clean aeroplane and free Wi-Fi was outstanding and the crew so pleasant and helpful.

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

The flight back to Dallas was delayed, which has happened to me several times with American Airlines. There was no announcement, no update sent out, no compensation offered for the inconvenience.

gave me complimentary food as the flight was not full and was attentive to my needs

It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

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.
