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

Overall experience was good but what really impressed me the most was the care the flight attendants took of a sick passenger who was sitting in front of me. The flight attendants would come and check on her quite regularly providing her support and comfort. Brilliant service!

Only answered OK and poor as there was no entertainment and I didnt have any food

Very good… seems the virgin staff particularly in the lounge and in flight exceeded expectations.

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

Qantas is always subpar beyond comfy chairs for a domestic flight

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Well my expórtenle with Qantas it wasn’t that good KLM from Bs Aires was delay Santiago Chile Qantas QF 028 was still in the airport but the crew didn’t opened the door for me soo I lost my fly And I stuck in the airport 13 hrs waiting for next fly by Latam Arline My question is can I have my money back for business class

It was ok, the additional baggage charges were a bit excessive given winter is a time for skiing. To have to pay $600 extra for skis was tantamount to robbery. Airlines should consider sporting goods as baggage. Likewise, they should consider increasing the number of bags allowed on international flights to known ski destinations.

Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Couldn't access entertainment on app as said in an email

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

A few more inches of legroom is all i ask

local frequent travellers know that Jetstar’s flights between MEL and LST are turnaround flights so those in the morning tend to run on time and become delayed increasingly through the day. We observed how the staff at check in and boarding try to assist, guide and facilitate travellers - they were courteous, efficient, amiable while enforcing Jetstar’s baggage requirements. They try to speed up boarding by having passengers board from both front and back. We would take Jetstar again.

The issue was a 4 hour delay to takeoff with very sketchy information provided about the available of the flights delay. Passengers were not informed of gate changes and how long the delay might be. It ended with a late night 2 hour drive to our home which was not ideal for elderly people.

Flight was fine with boarding starting a few minutes early. Not a fan of the crew pushing political messaging regarding indigenous naming of Brisbane city… really pushed it like I haven’t heard on Jetstar before.

Improved experience over our last years flight when also we flew local but on an international scheduled flight. The double processing is still unwelcome i.e. by security and then by border force having to produce a licence and boarding pass repeatedly on departure and return. Obviously suits the airline rather than the local traveller. The flight and crew were good though a helper on return was offhand having to push the wheel chair did the bare minimum we felt.

Flight was delayed both directions but once in the air was ok. Boarding out of Melbourne is just a mess.

Although a local trip via international flight it was fairly straight forward albeit more checks than desirable for local travel. On arrival Perth collecting luggage the trollies were hidden in one end of the long hall.

80 minute delay on departure based on two no show pax; removal of checked bags. Boarding very awkward, and waiting in terminal until specific rows called (not zones). Overhead not used for boarding, but specific staff member notifying people at the top of the stairs. Numerous people noted "this is confusing" on boarding. Seats ok, but entertainment (and food, and seat selection) all at extra cost. Smooth flight, and friendly neighbours.

Over four hours late. No entertainment without paying and same for food. Asked to check in at original time even though we were told it was going to be very late leaving. Way too long time to hang around the airport. Arriving to Sydney luggage did not arrive for an hour. Had to get staff to go and find out what was going on. All this made for a very long day and night for a eight hour flight.

I was disappointed to find that the QR code for purchasing in-flight entertainment did not function, leaving me without access to the amenities I had anticipated. (both flights)

I had opted to pay extra for a ticket on Jetstar A321-Neo in the first row, believing it would enhance my travel experience. Unfortunately, this was not the case. The constant line-up for the toilet resulted in people frequently standing next to me, causing significant discomfort throughout the flight. It was difficult to relax with the persistent disturbance from passengers bumping into my seat. Furthermore, I was disappointed to find that the QR code for purchasing in-flight entertainment did not function, leaving me without access to the amenities I had anticipated. Given these circumstances, I will not be purchasing seats in the first two rows in the future, nor will I choose to fly with your airline again.
