Stansted to Heathrow...Advice

Considering that flights to Germany can be had fairly inexpensively even out of Heathrow, that special flight out of Stanstead that he's determined to cross London to catch must be something special indeed.

I don't think it's particularly cheap or anything, just some of his old airship cronies are all flying in together and he's wanting to travel with them. Sort of silly, but you can't tell him that.
