It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

Flight was delayed by over two hours and that meant my connecting flight was in jeopardy but there was no acknowledgement or help from the BA staff

Club Europe is always lovely. I really enjoy everything about it. One thing that has changed in recent years though, is the swap to Prosecco from Champagne in the lounges. This is really disappointing. I really don’t like Prosecco, and always looked forward to a lovely glass of champagne in the lounge. Is it possible to change back? It does make the whole experience a little more of a luxury experience.

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

Crew was good. Seat was worn but overall okay. The infotainment system is outdated and needs to be updated. BA should provide free WiFi for club world/business class passengers.

I was unable to board the flight because I was unable to acquire a visa , Brexit changed my ability to get an ETA, I’m a Trinidad citizen and it takes weeks to get a visa

Flew business- but plane was dirty, food horrendous. Too many business class seats diluted service levels overall.

Not only were the aircrafts spacious, but the crew was friendly and efficient. I was so gracious for the included meals on the longer flight (8+ hours).

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

It was great. Enough space and room for legs . Great service to.
