Modal & commute
Congrats on getting yr post with "Imp" at our "Little Airport in the Country".
Most folks in the past have "sust" a share or cheap (not here) rental. Suggest try check the crew board for shares, if not call a few of the scheduling folks for assist. One way to make a few contacts on the way down. Way back when we started BEA Airtours we had folks coming from the West Country, North of the now M25 etc. No probs, everyone shared, partied, grafted, and had fun.
Good luck & enjoy Sussex.
