Great idea, but soooo obtuse. Maybe so the biz types will miss it but the occasional leisure traveller will throw BA an extra £100.

Comically ( ) / annoyingly a cheapo to NCE offers flexibility for an extra £243 (to B I assume) despite that being way above DEULGWUK. So how do I book DEULGWUK?

EDIT: Okay so DEULGWUK is not actually flexible.
