The biggest value proposition to me currently is the BWC policy. I can book safe in the knowledge that my money isn’t down the drain if I need to cancel or change.
After having my fingers burnt with Iberia, I’ll only book BA, OW partners on a BA code through BA and other carriers on fares below £50.
First Wing is also super convenient and generally hassle free. Makes a big difference to be able to whizz through the airport and get a proper breakfast on early flights.
