Qatar gave problems changing flight for emergency purpose and had produced all documents but they wanted further documentation which could not have access because at,a foreign country. Felt they don't care and it was all to do with money which had to pay.

I am a very experienced traveller. I always book an isle seat, especially for long flights (this was 12 hrs.), so that I can get up and stretch my legs etc. The couple sitting beside me were upset that I did not take the window seat. When it came time to sleep, the wife stretched out over her husbands legs, who was sitting beside me. This meant her feet were coming on top of my legs, and her legs were forcing her husbands legs into my space, touching my leg - I had to put a pillow between my leg and his leg. I asked the Qatar hostess if she could please ask the couple to change their positions, so that my seating space was respected, resulting in no body touching. The hostess replied that she was not permitted to ask the couple to change their positions and be more respectful. Fortunately there was another unreserved isle seat and I was able to move. Due to the fact that airplanes have become cultural melting pots, thousands of feet in the air, I think it would be peacefully beneficial too all, if a very discreet announcement could be made at the beginning of each flight regrading seating etiquette, respectfulness towards others etc. this could also be printed in the flight magazine. Thanks in advance.

Crew were supportive because pain in my heel and they ran out of food selection even though front of plane. Thanks especially to supervisor Jane.

Need to provide further quantity of non veg selection even though front of plane. Plus the taste of all food were Unsatisfactory and could not finish that was starving at end of flight. Recommend hire international famous gourmet chief. Removing casing of my tablet for Qatar security airlines into usa was painful that broke 6 finger nails. Need to warn on the website or ticket security requires remove casing at Doha to usa. Had no issue from USA TO Doha which requires no removal of hard cover casing.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
