Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

The staff was the best I have experienced as a frequent traveller in a long time.

The Achilles heel of the experience with Qatar Airways is the Doha Airport, especially for travellers arriving into Doha and not transiting. This airport suffers from being ambitiously big and the immigration into Qatar being overly time taking. At the end of my particular flight in which my travel was ending in Doha, the plane parked at a very remote terminal, from where it took me 30 minutes to arrive just at the immigration counter, with fast paced walking and the time on a train inside the airport. Then, at the immigration counter it takes up to a minute or more to process each tourist visitor,due to time taking face and finger scanning processes and langugage barriers if there are questions or information to be exchanged verbally with the officers. If several planes have landed at the same time, it is not unusual that one has to wait 45 to 60 minutes in the immigration queue. In short, the frustration of arriving at Doha takes away all positive vibe of the airline, as the airline and the airport are heavily intertwined and are marketed together.

It was ok, not much more can be said, as long as airlines/aircraft manufacturers insist on cramming in as many seats as possible....best of a bad situations, seats are simply too uncomfortable to sit in for more than a few hours. Lack of flexible headrests not a help on long overnight flights either.

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

The Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

Aircraft was spacious compared to American Airlines, food was great, entertainment was much better with a wide variety of options, and the crew was very polite.

Did not like anything. Seats were crammed, leg space was minimal and food was terrible. This was the first time traveling overseas in American Airlines and was the worst experience ever. Have learned a lesson to never travel in American Airlines.

Very unimpressed that I was dumped from the seat I had booked and paid for after check in. Apparently a family wanted to sit together, however as they all were adults I think they should have pre booked their seats like I did. I will be approaching Qatar for a refund. That and the dreadful state of the flooding toilets made me wonder how they managed to be voted the best airline. Not worth the money.

Everything about the flight check-in was smooth no line the plane is clean and bathroom

Excellent everywhere but Philly, the most rotten airport in the world.

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

All good. Loo’s weren’t great and as clean as i would like.

A great flight. The crew was excellent too. Of particular note of excellence was the gluten-free meal which was one of the best offerings I’ve ever had on a plane. Outstanding work, BA chefs.

I was put into business class. Wow! My flight attendant was great! The food amazing’

The gate at London Gatwick had confusing signs for the different zones and the staff seemed harried because people didn't know when it was their turn to come to the desk. Plus, with there were too many carry-on bag travelers, myself included. The charge scheme for checking bags is frustrating. If you travel light, you want the freedom to leave as soon as you deplane. When you are forced to gate-check your bag simply because the flight is fully booked, you lose whatever time you'd hoped to save because you're still stuck waiting for your bag to come off the conveyor belt.

I got stuffed on both flights into terrible seats. Second flight the seat didn’t even recline and fit s tall person, that’s very uncomfortable.

I arrived at Bridgetown only to fins that a suitcase was missing. It was left at Manchester. I had to wait wait 2 days before deciding on going to collect from the airport personally. I am not happy about paying for baggage at the airport. This I thought was included in the price of the ticket. Who goes away for 2 weeks and does not bring luggage. This was a total rip off and I am not happy. I need someone to contact me before returning so that I don't have to pay all over again to return homde.

Boarding market okay just because of the delay we had, but not related to the crew in any way…
