Very please with the seating that the Kayak staff booked for us!

I liked the movie selection and the speed getting the luggage. I did not like the fact that for premium they did not have a personal kit with toothpaste, I travel all the time in premium economy and bussiness and althought the kit might bot be the same at least you have the smalles kit in premium economy. I did not like either that because i was in the last row of premium economy nothing made it to my seat. They run out of the food I wanted ( it is a surprise because there were only 6-7 rows. They would run out of orange jouice were thy were passing water/orange juice around, they run out of some alcohol. I am undertand running out of it but I don’t understand why mot getting kore. The service I received in row 11 was different from the service in rows 7,8…. Also the screen on my tv was broken. It did not respond to touch. So, in conclusion, if I compare my flight going to Europe with an American airline plane in premium and the one with British, British expereince was significantly much worse. This company is declining fast.

The crew on the flight were not particularly pleasant and fluid restriction was an issue. I was not allowed to fill my water bottle. Crew didn't check on passengers other than meal service.

BA is a fine airline. The problem lies with XCOVER INSURANCE, that KAYAK uses. Very poor service from insurance. No telephone number to contact XCOVER. Their replies are inadequate & overall very bad insurance. I wish kayak uses standard insurance company., such as AIG.

British Airways offers amenities subpar with all other airlines flying internationally. Sharing tis based on my experience with flying at least five other airline between IAD-DEL in the last six months.

Worth every penny to upgrade to BC. Treated and felt more like First Class

I missed my flight because I was sick and the medicine the chemist provided made me sleepy. I had to pay $3500 to get home because you classified me as a no-show and would not listen to me otherwise. In addition you wanted to route me through Dubai, which was under siege by the time I arrived home and would’ve been in trouble. Had I taken that route

Limited entertainment. Music - very limited variety of music. Suggest more options in Hindi, Telugu, English for flights leaving from Hyderabad.

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

Food was good. For a long haul flight, there was “0” zero entertainment! What a disappointment. I do try to avoid BA. Next time its Emirates via Dubai to Cairo.
