We flew from London Heathrow to Toronto 2 weeks prior to this flight by Economy. No complaints, good service etc, to be honest a great flight. Well as we neared completion of check-in at Toronto for the return flight, the BA woman asked if i’d Like to upgrade to Premium Economy for myself, partner and son for $279 Canadian. Having not flown with BA before I didn’t know if this was a good deal or not, plus having spent my holiday money I initially said no, but thought why the hell not, so stuck it on the credit card. The flight was similar to the flight out with regards to service etc except much more room for the body. However after getting home and checking my credit card statement, it was $279 each, £166 x 3....... Shocked or what, felt like I’d been duped.... Got in touch with BA, there not interested.... So the moral of the story is check and double check what your being sold, I Reckon the flight was over booked with regards to Economy passengers and before they had to upgrade people free of charge, they relied on idiots like me.... Still had a great holiday though.....
