These are a bit different from regular Advance fares elsewhere on the
railway in these respects...

specified time).

I missed another important feature - if you buy a return 'Advance'
ticket (at £24 - or £22 from Tottenham Hale), then the return portion
can be used any time within 30 days of the outbound travel date - i.e.
you don't have to specify your return date.

Useful if for example plans change and passengers change their flights
(easyjet has flexible fares aimed at the business market, and the 'new &
improved, cuddly' Ryanair is set to introduce them soon), or there's a
significant flight foul-up of some kind.
