Maria,
Welcome back.
Just to make you aware, EMA is expensive but BHX is considerably more. Unless EZY are getting a big discount, i dont see them uprooting and going to BHX as a full base move. It would be economic suicide. if the EMA routes are performing well and making the company money, they arent going to upsticks. EMA and BHX could work together for EasyJet even tho im not bothered about BHX in anyway. Havent flown from there since 1990.
If EZY move they will lose alot of loyal customers from the East Midlands.
