I booked a trip LAX>LHR>HAM on Dec. 22nd and then HAM>LHR>PHX on January 1st. Both were WT+ purchased upgraded to CW with miles. About 2 months ago I got an email that my HAM>LHR flight coming back was cancelled. I called BA about it and there were no other flights that day that would let me make my connection. I was willing to fly a day or to later and would consider both PHX and LAX (as my final destination is SAN). Eventually they found me a return HAM>LHR>LAX on the 3rd but it was only available in FIRST. They gave me a free upgrade and booked the trip. That's what I call service. Needless to say that will be my first time ever flying FIRST on BA. I'm excited!
