In May, we booked first class seats with BA through American Airlines. {BTW, American has top notch customer service and when you make a change, refunds happen automatically and seamlessly.} We got Covid in Amsterdam and had to stay longer than expected. Therefore, we had to change our flights twice, ultimately flying AA. I waited a couple of months for my refund from British Airways and finally called. I was told I had to email my request which I did along with my receipts. After multiple requests they have refunded about half of what they owe me. But the clincher is you cannot talk to anyone about a problem and even email replies say "Please don’t hit ‘reply’". Customer service is literally non-existent. I have emailed the execs whose email I have found online and once again received a "Please don’t hit ‘reply’" email, standard response saying, in essence, "you will hear from us when we get around to it". Truly, I have had better customer service from cut-rate domestic airlines in Mexico than from BA. I urge everyone to use any other airline if at all possible.
