I don't think BE will cave in they have seen off opposition in the past
I can't see a big drift to EI. Why? BE have their connections via LGW and codeshare with BE, yes their profit and numbErs will reduce.
EZY have put on an extra flight from mid December, nor withdrawing from this route but increasing.
With SEN doing well and extra weekly flight on friday to luton LGW I believe in number terms for EI will just be oK nothing special
LHR will reduce for EI because of BA and forget LHR unless you favour LHR or are connecting EZY want BUSINESS pax
