P_M_: no problem catching a ride on my thread. I have my questions answered. In fact, I called British Air to see if they had transportation from Gatwick to Heathrow. BA does not, but told me that jetlink coach goes between the 2 airports for about £17 each.This must be the coach that you, Janis, were talking about. Again, thanks for you help ! One more detail, crossed off my list. There will be more though, so stay tuned !
