The staff was very nice and helpful. Some of the best crew I have met.

Bad experience. The seat room are very tight. The food is not good and the breakfast has no hot drink.

Excellent. Thanks to United Star Alliance, since economy was overbooked, I’m grateful to have been upgraded to Business Class.

Good plane, excellent food, crew and entertainment. Seats in business could use an upgrade

Disaster. Downgraded. Zero apology. No effort or coordination between gate and crew. Awful seat blocked by door emergency slide box. Iberia is a mess. App never works. Avoid this airline.

We departed late but made up most of the time in flight. Our ticket was pure economy, so it wasn’t anything fancy; however, I heard that we arrived in Madrid at the exact same time that First Class passengers arrived! Overall, our experience was similar to what we had on other American Airlines transatlantic flights - good value at a reasonable price. We were even able to get our carry-on baggage onto the plane without needing to gate check it.

Flight was OK. Waiting for luggage in Madrid for 55 minutes, unacceptable

Transportation from gate to airplane was poor we stayed in hot bus for 20 minute no vantilation

The crew were friendly and helpful. Iberia lost our luggage on arrival, Friday and we didn't get it until Sunday at 10:00 p.m. local Malaga time. I also paid $382.80 for seat assignments but two out out of the four were not together. Iberia mentioned that it was because the plane was delayed in Madrid before our flight began in LAX. They should compensate us half of my payment.

We liked the flight but while we purchased an aisle seat, our seats had a different configuration on this flight. A fellow passenger suggested that the airplane had been changed. Too bad we were not informed and had no chance to modify our seat preferences. We were stuck in the window and middle seats with no chance to walk around and go to the bathroom without disturbing our sleeping fellow passenger.

main meals are horrible but then you dont fly for the food

It was good. Couldn’t Check in online and select seats

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

⭐ British Airways Review — A Journey of Highs, Lows, and Lessons ⭐ I recently flew Business Class round-trip from Boston to Mumbai with British Airways, and my experience was a tale of two extremes — from disappointment to exceptional service, and then back to inconsistency. Boston → London: A Surprisingly Poor Start My journey began on a disappointing note. On a 6-hour Business Class flight, I was surprised to discover that there wasn’t a single proper vegetarian meal option available. I was offered a few bakery items only after repeatedly requesting something to eat. The flight attendant shrugged, offered no solution, and eventually — quite literally — threw some bread at me after much delay. This was not only disheartening, it was extremely surprising given my wonderful Business Class experience with BA last year. I stepped off that flight genuinely hungry and had to make a mad dash to the lounge just to get a proper meal. London → Mumbai: A Complete Turnaround The next sector restored my faith in British Airways. The entire crew was warm, welcoming, attentive, and genuinely caring. A special shoutout to Phiroze and the entire team serving the Business Class cabin — their professionalism, hospitality, and thoughtful service were extraordinary. They truly embodied what makes British Airways a global leader, and I am deeply grateful for the experience they provided. This is the BA I know and love. Mumbai → London: A Strange Meal Schedule This sector was generally fine, but the meal timing was puzzling. Lunch at 10:30 AM — for a Business cabin — felt unusual, and most passengers, including myself, barely touched it. The rest of the service was smooth, but the scheduling definitely needs a rethink. London → Boston: Mixed Experience Again The flight itself was decent, but the Business Lounge at Heathrow for this leg was a letdown. Arrived during lunch hours: no hot vegetarian options available Lounge area: dirty dishes everywhere Even after politely alerting the staff, the dishes were ignored and left uncleared For a premium cabin passenger — and at one of the world’s busiest international hubs — this was disappointing. Overall Impression My journey with British Airways felt inconsistent — two great sectors sandwiched between two that fell short of the BA standard. When BA is good, it is world-class. When it misses, the gap is noticeable. I genuinely hope the airline takes this feedback as constructive insight. I continue to believe in British Airways, and I commend the outstanding crew on the London → Mumbai sector — they were the highlight of my entire trip. With a little more focus on vegetarian meal availability, lounge service, and consistency across crews, BA can ensure every Business Class passenger experiences the premium journey they promise.

We were in business class and I had seat # 1. This was a night flight and after dinner was served, lights were dimmed and I went to sleep. The crew were loud and noisy so I didn’t get much sleep. I expect the crew to enjoy themselves but would Appreciate some decency in staying quiet while the passengers sleep

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

Great on board entertainment Tasty food Cattle class obviously crammed but not as bad as shorter hall flights

Logan gate staff was unhelpful. Arrived early, come to find out the airbus scheduled was reassigned and I did not have a seat. The desk agent spoke to his supervisor who instructed him to give me a boarding pass to get up to gate area, he was polite. At the gate the fellow was sitting to the side with two other BA staff . I asked him if he could help me, his answer was” we are on a break, we are closed” then turned his back. I am almost 70, drove 4 1/2 hours to Boston and had been looking forward to this trip for 5 months. I have worked in service many times in my life and this is not how it is done. I eventually (1/2 hr) before boarding was able to get a seat. The rest of the flight experience was unremarkable.

The boarding process was chaotic at LHR and the seat was not as comfortable as other airlines....

Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.
