It's nothing to do with FR being better than EZY. Just making a valid point.
Redeployment of aircraft I agree isn't uncommon and makes perfect sense in some cases but there should be a mix of that with some actual growth. It has been a common theme in the UK for EZY over recent years. Rarely, other than at LGW, has EZY actually delivered any growth at all.
FR have been able to and continue to grow very strongly at STN without it having an impact on their LTN and LGW operations. In fact, FR will increase at both these airports too this year.
A similar thing has happened in the North-west of England between LPL and MAN and also in Scotland regarding GLA and EDI. EZY have grown in recent years at MAN and EDI but most of that is only offsetting cuts in LPL and GLA.
FR by comparison have cut back in LPL and PIK but the growth bought to MAN, GLA and EDI over the same period has more than compensated for those cuts and quite significantly. That too shows your redeployment of aircraft but there's growth bought with it as well which is equally as important.
That's the only point I'm trying to make, not a fight between one airline being better than the other.
