Boarding was over 3 hrs late and we didn’t land until almost 1:30am

2.0 MediocreKristen, Dec 2024TSV - BNE
Read more Qantas Airways reviews

Boarding was over 3 hrs late and we didn’t land until almost 1:30am

I disliked the fact that they forced people to put up their seats during meal service

Headphone jacks worked poorly, seat recline was broken. Planes were rundown.

Delayed and missed connection, was not re-booked like other travelers so ended up being stuck for several hours due to no one handling my booking.

American Airlines was their usual junk service — but at least it got us down to LA. I was more irritated that while they codeshare with Alaska Airlines in Seattle, they could not out our flight on one of these, opting for one of the small SkyWest operated American Eagle flights — and causing a 14 hour layover. Which I accepted due to a $2000 difference in airfare — that said it was irritating for a flight that usually would have cost around $100 extra, if that.

same as previous comments. i hate being on a plane that long. no problems w/anything else.

It was very nice. I will try to fly with Qantas whenever I can.

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

Much better than I expected for such a long flight.

Flight was cancelled about 1.5 hours before departure. Replacement flight provided scheduled 1 hour later. Late boarding, late departure and arrived Melbourne nearly 2 hours after originally scheduled.

Flight was delayed two hours. No snacks and no tv screens. My bag got stuck in Chicago

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

I completely missed my flight because the first leg was longer than planned. I had to sleep overnight in the airport because no accommodation was provided and then sent to Trinidad in the morning with an anticipated 7 hour layover before my flight to Georgetown which was now with Caribbean Airlines. I tried twice with customer service to see if they could put me on an earlier flight which had seats available but was told it wasn’t possible.

Food is terrible. Flight is outdated and seats are not comfy.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The aircrew was solid, the flight was chill, I had no issues. The gate agent was not the best. I was trying to use a military bag upgrade to move my bag from under the seat to the overhead bins and he told me there’s no overhead bins on the plane, argued with me why booking put a military member in basic economy (I don’t really understand this) and made it an issue to even try to help me stating I’d have to call reservations to get a bag upgrade. When every other agent with United can add it at the gate, this man couldn’t be bothered.

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

You were more on time than United. I'm so over united delays.

Good communication at the gate and very nice crew in the flight

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

My seat was wonky...hard and not much padding. I sat next to the Jumpseat for the flight attendant. Thoroughly enjoyed not have a third seat in that row! Flight attendants were amazing. I couldn't answer the "food quality" question as there is no food served on my short flight. I commend the pilot as I know it was super gusty when we landed. Thanks

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.

I had a very unpleasant encounter with one man from customer service: he was extremely rude and miserable. And his condition was reflected on his decision to send me to the worst airport hotel and get an awful flight connection. My hotel shuttle had never arrived and I had to book another hotel. People served by other representatives got a much better treatment and deal.

AA is always pretty solid. Was on time all the way around today so can’t complain!

Ok. Got us there safely and a bit early. Need food available on this long flight. Almost 3 hours.

Flight was delayed by 11 hours. Flight agent finally had to rebook us, but did not rebook fully correctly. We had to pay out of pocket to get to the hotel they booked us and couldn’t check in the next day online because the next day’s agent said they didn’t complete the process the night before.

1. The PA system was painfully loud. 2. Overhead bin #33 was missing—I find this troubling.

We have already filed a formal complaint with Air Canada and are considering filing a complaint with the US Dept. of Transportation. Air Canada was impossible to reach in the two days leading up to our flight despite multiple calls and waits of more than one hour. Their website is designed to prevent reaching anyone and simply puts you into one doom loop after another. In the end, due to Air Canada's lack of communciation and unresponsiveness, we could not take this flight. Depending on how Air Canada responds to our complaint, we may never fly this airline again and advise the rest of the world to do the same.

the service was fine but would have which that the audio for announcement is better.

My wife was in a wheelchair. Most accommodating and kind staff!

The flight was delayed 2 times. The 2nd time with no knowledge of why.

No entertainment what’s so ever so you may want to prepare yourself. Our flight was delayed.

I had a disappointing experience at the San Diego airport with one of your gate agents. Despite being in Zone 4 and traveling with a standard carry-on bag that has never been an issue (30 flights in Q4 alone), the tall, blonde gentleman forced me to gate-check my bag. When I politely asked if we could verify the bag’s size, he became confrontational, even threatening to deny me boarding twice. His behavior appeared erratic and unprofessional, projecting a negative attitude onto passengers, as if he was going through something mentally. Notably, there was ample overhead space once all passengers had boarded. In contrast, the tall, older Asian agent handled the situation with professionalism and calmness, making a clear effort to de-escalate. As an avid traveler, this unnecessary inconvenience set a frustrating tone for my trip to Asia.

This leg was run by United. Food was ok and the regular menu was actually not good ( Hindu meal was fine). Crew was fantastic

The seats are soooooooo small in economy. I was offered no tea or coffee in the am. When I asked was told that it was too late. The plane was 2 hours late leaving.

Very good. Very efficient. Entertainment was not functioning both ways which was disappointing.
