Well one 'myth' in the Independent article is at least partially true:
Can you get on a plane without a passport? - whilst the article ackowledges that 'some' airlines will permit access to domestic flights with photographic ID that isn't a passport, they can't have flown domestically with BA or BMI. Both allow airport check-in and boarding without any photographic ID - provided you check-in with your FF card. That's certainly been my experience for years now anyay.
