I decided not to board BAH return flight to LHR but instead I am flying from SIN to Japan with Korean Air (I have a "personal policy" of not flying OW if alternatives are substantially cheaper.)

Anyway, the reason I mention this is that it caught my attention that Korean charges for "no shows" - I never saw that before.

I think if BA started doing this, I'd not be too happy - after all they are making more money by not flying my overweight* (fat..) body , thus saving on fuel on a booking that has been already paid for. I guess it's about opportunity cost to resell the seat but I'd not be too happy if BA adopted such policy (though I don't think this would ever happen. But who knows). What if a connecting flight on a separate ticket is late? Presumably Korean would charge the penalty.

Or should BA do something about "no shows". Personally I think not, being one of the frequent culprits recently
