I too work for Easyjet...................but i don't own the airline and I speak using facts.
FACT: DSA is the main airport for Doncaster!
FACT: DSA is not an Easyjet base. As others have clearly stated.........
-There are no Easyjet employed ground staff
-If you take a flight from DSA your crew will be LPL based(supplemented by MAN)
-There isn't a crew room or other administrative means that are the fabric of an airline base.
-Take a look at this months inflight magazine. Easyjet Bases are indicated by a large DOT. Airports served by Easyjet but not a base are indicated by a small DOT. DSA has a small DOT. FACT!
