Sorry to have another thread on BA's poor experience. I don't post many complaints but this one has made me decide it is no longer worth flying BA to keep my GGL status. So this year will be my last GGL year.

I had a revenue F ticket from DFW to LHR. I had to change to a flight one day earlier due to a meeting schedule change. There was no F so I changed my ticket to a J class ticket. Upon arrival at DFW I checked ExpertFlyer and found F1 A0 so I asked to pay the difference back up to F (previously they refunded me the F->J difference). This is where the fun begins. First agent said no seats in F. I said I can see it and even went to ba.com to see I could purchase a ticket and showed them I could buy it online. So the agent told me I should just buy a new ticket online. I asked why would I throw away an existing ticket when I can pay the fare difference?

I quickly realized that BA had gotten rid of all BA staff at DFW. I know this is cost cutting but the BA staff there before were brilliant. The DNATA staff there now are clueless. I asked for the manager (dnata staff) to check but they said she was busy. So after 20 minutes the manager finally came out as I was still hoping. By the time she came out the F seat was gone. No one else check-in during the time I was there in F or J. She said there was no F seat and the flight was oversold. My biggest complaint was just her arrogant attitude that she knew everything and I knew nothing. BA should have one of their own BA managers / staff at DFW to manage the flight. That is what I've seen in other airlines where they retained at least one of their own working with an outsource ground team.

So I guess they upgraded another person from J to F even when I was willing to pay revenue. I'm sure dnata staff have no incentive anyway to help BA generate more revenue.

Other incompetence was shown when they entered my KTN (Tsa Precheck) number into my FF number so my boarding pass showed BAGold###### but the number was actually my KTN number. 3 agents tried and could not fix it. So I went to the gate and first agent said she is too busy and to fix it upon arrival in London which I knew was not easy or possible. Finally found another agent to just delete my FF number so I can send a retroactive claim later.

Flight itself was fine no issues at all.

London arrival was a mess as I expected. E-gates were great but baggage took over an hour. My Apple Airtags showed the bags had arrived at the baggage system (we were parked at C gate) over 30 minutes ago but no one loaded the priority bags onto the belt. Another flight that arrived later had all their bags out on the same belt by the time our bags came out.

Went to BA Arrivals, showers were broken and I needed a shower before going to my meeting so had to go to Sofitel to get a day room for a shower before heading into town for my meeting.

Overall, just a poor experience and made me decide after all these years being loyal to BA it is not worth it anymore. Luckily, I'm at a stage in my life I choose my carrier regardless of price but sad to see the decline of BA.
