For me it works to have both cards. Vague strategy:
- BAPP
- Amex Plat
- EasyJet Plus
Just over £1k all in.
Travel is about 50 flights a year, 20ish on EZY and 30ish on BA (mostly short haul, occasional long haul thrown in). Credit card spend (about £20k) almost all goes through the BAPP so enough for companion voucher and return of about 40k miles (after extra bonus on BA transactions). Amex Plat is worth it for me - various credits pay for the cost of the card quite easily, and the Priority Pass gets well used on the EZY flights. EZY Plus at about £215 makes a big saving given that I’d otherwise spend £40ish per EZY leg on seat selection and cabin bags (so saving about £600).
