Overall great! They could add more entertainment option. They kept running out of vegetarian food options and I got travel packs. This happened on all legs of the flight. Need to plan for it better - I am sure you have some data analytics from all your travels.

Horrible as a connecting passenger. The airport experience is horrendous in Madrid. Once on the flight everything was fine. Stop selling connecting flights through Madrid with less than 2 hrs transit time!!

They can improve Everything, a 12 hour flight has just 2 meals and the meals are 7 hours apart, wtf are they thinking. At the very least they should have 2 refreshments like some small snacks with some water or some other refreshments since there are people travelling with medical conditions. The services and seats were genuinely horrible

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

ok. It's a short flight and it was delayed, hence the ok rating.

It was good. I really liked the breakfast which was served.

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

The seats were uncomfy and the food tasteless, crew clueless

They ran out of earphones so my 3rd daughter couldn’t use the on board entertainment the entire flight. They also ran out of food choices (chicken or cheese) by the time they got to the last few rows, so my oldest daughter, wasn’t given a choice. Luckily she isn’t a vegetarian because they only had chicken left.

Ground staff bangalore could have been more attentive to business class passengers
