No one mentioned Continental's 757 STN
service that got cancelled post 11/09? Odd.
Lufthansa did indeed start up all routes that were served from Stansted by other low cost airlines, and a few more, at (back then) spectacularly low fares. One of the results was that their GBP 64.00 student fare on LON-MUC
was cancelled in favour of widely available STN
fares (GBP 78.00 - back then Go's cheapest fare was GBP 80.00). Go retreated from MUC
for a year, and other low-cost airlines suffered too. Lufthansa then let (or made?) British Midland operate most of these routes, but when the LCCs returned with a vengeance (Go started offering GBP 55.00 fares after they returned), they pulled out. Oddly enough, their student fares never returned (at least not in the UK, AFAIK)....
Scandinavian still serve STN
, I believe, and so does TK
Stansted is actually the most convenient airport for Cambridge & other places, so I honestly think it has some potential for LCY
-like full frills, full fare regional operations.
