Leg Room and IFE
A couple of posters have mentioned MON legroom and compared it with EZY legroom. Monarch's minimum is 28". The minimum for EZY is 29". However MON do have 29" in some of their aircraft (and more room on long haul aircraft but that's not relevant on an EZY forum). I will try and dig out the CAA statistics.
Also with regards to IFE, it has been confirmed that easyJet will be using it on the ex GB fleet. EZY have recently recruited someone to be in-charge of IFE.
IFE will soon no longer be free on Monarch, even on their scheduled services. It has been confirmed they will charge for headsets. I am not sure if this has started.
From a passenger point of view, apart from allocated seating, I think IFE was one of the key differences between Monarch Scheduled and easyJet. Now that easyJet are getting it, I think it is becoming harder and harder to tell the two airlines apart. Well, apart from the horrible Orange colour!
I would personally be surprised if EZY do buy Monarch. Will keep my ears open!
