Airline reviews

They are still charging me after taking 466 and 833 for round trip from AR to to Bradley airport from 19 to 21. Then poor experience. Am hurt and I will say it on social media. Please stay away from this airline. I see in my bank account they are still taking 644. Am trying to stop it. I used to fly United airlines and I suggest that if you don't want extra charges and good service you go back there. American airlines delayed my flight again and I was late for my meeting, no recompensation but charging me over and over.

They changed our Gate 5 times, and concourse twice. Changed our seats twice.

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

The chicken adobo was a little too spicy but good otherwise. My personal opinion. Movie selection could be improved, too many horror movies. Could add a few more chick flicks! The flight was bumpy at times. We arrived a little early too! Flight attendants friendly.

Again flight was awesome except British Airways lost both gate checked luggage’s. Still missing

Pitch was very small. Knees were on the seat back in front of me.

really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE

British Airways staff are very polite and willing to help.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

The flight was initially delayed, then cancelled. American Airlines says the cancellation was weather related, though the actual weather was not bad in both Washington and Providence and between. There were very few cancellations that day. In fact, AA2120 from Washington, DC to Boston flew with a minor delay at about the same time. So, the weather somehow affected only this particular flight AA5230. The next available flight was the following morning. The American Airlines refused to reimburse accommodation (hotel at DCA)

Flight was good but seat in 12D was not comfortable, better on the Airbus 321 from Tampa to Charlotte. No breakfast was served before landing in zLonfon only a coffee and orange juice.

I was transferred to an American Airlines flight. The boarding was late and unorganized. The seating was extremely tight and uncomfortable. Will not use AA again.

The entertainment selection was ok, but overall not bad! The crew was great.

Good crew and boarding process. Horrible food and one of the most uncomfortable aircraft seats I have ever sat in. The cabin temperature was warm which made it hard for my family to sleep.

The check-in of my luggage was terrible. When purchased my tickets, one luggage and one carry-on was part of the fight. My flight was switched from British to American Airline. During check-in of luggage at the airport, I was denied and had to pay extra $75. How do I get reimbursed for this extra luggage payment?

More Indian vegetarian food options would have been better Availability of seat selection free of charge 72 hours before departure would be great

This was the second time on BA, food terrible, bathrooms gross,( granted, that was mostly due to the disgusting children urinating all over it)boarding was late and disorganized. No gate issued until last minute st Heathrow, bad system, caused undue stress. Seats were painful, that's what you get for traveling like a poor in economy, right BA? Should have been able to afford business or first class if you want to actually be able to walk upright without back pain after a trip.

The flight was delayed twice and because of that, we missed our connecting flight. British Airways then attempted to put us on the last flight to Milan from London which would have kept us in the airport for 12 hours. We had to speak to several levels of bureaucracy until BA management let us fly on a flight that only kept us in the airport for two hours. If there was an earlier flight, why weren’t we put on that flight from the start? Unacceptable behavior from what was once my favorite carrier.

The payment system was not working so was unable to connect wifi the entire flight

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.
