Hello there.

Currently having a nightmare trying to work out the best fare combo
from Belsize Park to Gatwick Airport, at various times of the day (i.e.
sometimes in the morning peak, sometimes not).

Two quick questions:

1) The guy at the desk the other day offered to sell me a ticket from
Belsize Park to Gatwick (Thameslink), Cheap Day Rtn for 11 quid -
seemed like a good price, so took it. Is this ticket likely to be
cheaper than Oyster to the NR terminus, and then normal NR CDR etc. to
Gatwick.

2) Doing the reverse journey (almost - Gatwick to West Hampstead), the
bloke at LGW gave me a Day Travelcard to R1256 instead of the single.
On the Y-P railcard, it was cheaper than the single to West Hampstead.
Anyway, is there any way to use this sort of travelcard in reverse -
i.e. get it issued at the 'London' end of the journey, and use the
Railcard bit, then the journey to LGW and back, and then the railcard
bit at the end.

Any advice on this journey - currently driving me insane (how can
London Bridge to Gatwick have about three different prices for each of
SDS, SDR, SOR...)

Many thanks

Henry
