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.

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.

The internet was working on both sectors of the flight so hard to take the flight if you are on business.

Delays on take off, delays at gate on landing, lugging lost to the ether. power on seats not working, couldn't work due to that and no WiFi. The crew was great and boarding was orderly if confused and rushed.

Mumbai airport is a nightmare! Especially going from domestic to international terminal (2). I almost missed my flight. Then i could not check in because I purchased on kayak to British airways and my first flight was an indigo (non partner). So they called me when I was at the security outside the terminal and told me I had a middle seat, not what I paid for! After talking to the desk agent, they could not help but it finally worked out. A bit stressful for no reason. Probably never buy from kayak again this type pf complicated tickets (multi cities).

My flight was delayed and my second flight missed despite a three hour connection in Düsseldorf. My luggage was lost and it took three hours to recover which was actually unfortunately very much barely possible. I needed to rebook a flight that was three times the original cost of the original flight which now I need to go back and recover from the airline. Terrible experience,

Easy checkin, fast luggage drop off, quick boarding, early take off and arrival. The perfect flight! Thanks

Nice to have reclining seats for a change and great to have internet access

Tivat airport really needs to up its game W Eurowings needs to provide support at luggage collection

Delay after delay: no information besides what my Kayak app provided was provided about the delays. The plane was at the gate. Also, the gate, 100A, was incredibly warm, and the sun was beaming in. Boarding was disorganized with no groups announced.

Kayak - EDreams - Eurowings need to define clearer the hand luggage terms. I asked for add. hang luggage got charged by Eurowings for having add. hand luggage that was not included in my booking. I travel alot! I know the size dimensions never paid twice for hand luggage and cannot chase Edreams or put Eurowings in the wrong. Also there was severe delays on this flight. Issue getting bus on arrival and missed connections. Unfortunate will not use Eurowings

We checked in 4 luggage and only got 3 back & lost our 4th luggage. Our flight was from berlin sept 22. We arrived Copenhagen but only received 3 luggage. Missing 1 still 24 hrs after our arrival and our Cruise will be leaving tomorrow 9/24/2023. This is the second time that our luggage gets lost/delayed in Copenhagen

No food on plane.. flights scheduled 55 min..everything is very expensive on aeroport

Filthy plane, obviously not cleaned properly between flights, food crumbles in seat and carpet

Smallest seat I have ever seen. And they had a label with more Legroom but in fact where really tiny.
