| Los Angeles to London. I booked with AA, LAX to LHR round trip very far in advance. BA is AA partner. Paid for the BA seat selection early to get good seats. BA canceled the flights (coming and going), BA did not inform AA or me that the flights were canceled. All of my text and phone number was entered with BA with my passport number. They should have contacted me. I found out a couple days before my flight because I happened to call to do a meal request. It turns out that BA shifted to smaller planes and I actually spent six hours, over two days trying to get flights on the days I needed to catch up with a tour. All they said is we can't help you. I kept calling and calling and got seats on the days I needed but they were the worst seats on the plane and because they were smaller planed, Premium Economy was awful. Food was terrible. We had pre paid $276 to choose seats. There were no good seats left. We ended up on a night flight right next to the toilets. Which meant the smell, people are bumping into you, the lights going off and toilets flushing for 9 hours. Same seats coming home. I would have been better off flying in coach. I have spent a month trying to get refund for the paid seat selection. I tried to get this before my return flight started because I was still calling and calling to get seats away from the toilets on our return flight and to get our refunds.They wouldn't refund. After returning, I made five phone calls and spent 30 mins filling out a detailed request online. Called again today, was disconnected twice and told there is nothing I could do. It is possible I may get a response in a month regarding my email request. Don't ever fly with them! They used to be the finest airline in the skies but now their system is broken and there is no such thing as customer service. If you have a problem, you will be up a famous creek without a paddle. They have an endless loop of calling, waiting on line, their agent's can't or won't do anything but sell seats. I spoke to many many supervisors, no results. There is no one to solve problems. They pass the buck, have you fill out forms online and no one responds.
