Extra seat belt across the chest 10 minutes before taking off and 15 minutes before landing seemed excessively safe.

Extra seat belt across the chest 10 minutes before taking off and 15 minutes before landing seemed excessively safe.

My case was missing a wheel on arrival Heathrow and the staff were unhelpful when i tried to get some compensation stating it was not sufficient damage, i only wish that they at some point have to deal with the same situation it put me in, maybe they would change their attitude but overall it was a good flight

We are satisfied with the cabin crew serviceand the quality of meals served.

The aircraft was really old, the staff demotivated and the overall United airline service is horrible

Lunch Food was tasteful and had variety. Seat was comfortable. However, when I was reserving my seats during booking, the seat configuration showed was 3-3-3, but when I boarded it was a 2-4-2 configuration? Also during booking, I had also bought travel insurance together with my TG booking. However there was no confirmation of my purchase from Allianz and TG. After several emails with TG contact, sales, reservation and Allianz was i able to confirm my insurance purchase. When the policy was issued, the birth dates of me and my wife were wrongly stated and I had to go through another round of emails with Allianz to get it corrected. Otherwise any claims would be void! It was indeed not a very good booking experience!

Check in was a disaster. 90 minutes and only 2 economy check in desks open. Had to rush to catch the flight.

I couldnt go on this flight and lost all my money over 1,000 UK Pounds as my visa to Myanmar was not accepted :(

Thai Airways is one of the best airlines in the business. Looking forward to fly again with them.

food poor i said chiken i got pack a pow breakfast lousey .job to explain wot it was ...

No working jet bridge to deplane, with priority customers deplaning last. Followed by bus to terminal.
