Airline reviews

Even in business class, no 2 members of our family including kids were able to sit together. I booked the tickets months in advance. The all my luggage was left in London and arrived 2 days later. It took hours to report the missing luggage at the airport and 3-4 hours to recover one of the bags from the airport with mind bending amount of paperwork. Worst experience ever, I would seriously reconsider traveling by British Airways again.

Even in business class, no 2 members of our family including kids were able to sit together. I booked the tickets months in advance. The all my luggage was left in London and arrived 2 days later. It took hours to report the missing luggage at the airport and 3-4 hours to recover one of the bags from the airport with mind bending amount of paperwork. Worst experience ever, I would seriously reconsider traveling by British Airways again.

Crew attentiveness and service as well as the quality of on board dining could be better. Seats and controls are very dated.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

Overall, the food and entertainment were great. The staff were amazing, polite and professional. They did not have WiFi on board on this leg but that was okay. There was a delay in boarding from London and landing at Mumbai airport but the pilot communicate DC the reason for the delayed landing. They even sent us an apology afterwards for the delayed landing.

Big queues on arrival at airport despite having already checked in and only needed to drop bags off. Flight delayed which impacted on connecting flight.

I was in a bulkhead seat and my tray table wasn't level. Eating was difficult.

Nice lounge but had a 5 hour layover which is a lot

Flight on time and priority boarding worked. I travelled economy although business was available as no flights are cheap these days and at least with BA loyalty card I get a baggage allowance for nothing. That made the flight comparable or even cheaper than the ‘budget’ alternative. As for catering and entertainment - not on a BA short haul economy ! At least we were offered biscuits and water! Catering for economy short haul has been reduced to the minimum - no tea or coffee or other drinks than water (from a large bottle with a paper cup on offer). They will say this is better for the environment, which it is, but proper waste management is still needed for empty packets etc. so actually it’s a money saver.

Audi visual not working for a whole group of seats in first class. How does a plane leave the main hub in such poor condition? How much that we can’t see so immediately is also compromised?
