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.

The worst parts were not BA’s fault. The chaos of passport control etc was totally unnecessary. One of the Officers who was stamping passports (remember that) told me that if I had a problem, I should contact Boris Johnson! Secondly, the distance from the Lounge to the Gate was beyond acceptable. All in all, the issues with immigration and emigration and the hikes within the airport mean I won’t be returning anytime soon

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).
