Great experience, thank you.

Headphone jacks didn't work (seat 59D) so was unable to use entertainment system. Seat power only worked after my unit was rebooted. Disappointed that BA no longer offer free seat changes for all classes of tickets (and the default seat is always horrible). Will consider other options / carriers next time.

I’m glad WestJet stopped charging for earphones and give them out for free like Air Canada always does. As well as free meals on long flight

Not bad considering all airlines are money grabbing sociopaths, but at least Air Transat throws in a meal and a glass of wine as a bonus with their low fare so they win my vote as the best of a bad lot.

Flight delayed 2 1/2 hrs due to storm in London. Pilot came out to explain what was going on and stayed out with passengers to answer any questions. Found this very professional and considerate!
