wizzair
Wizzair will have 6.5 million available seats at LTN this year. If Easy have A/C 22 and 23 joining the fleet then LTN should reach over 16 Million this year end.
I believe the loss of Copenhagen flights will no longer be detrimental to passenger growth.
Lets not forget both LHR and LGW are both reaching saturation at this given time.
It would be prudent for the current operators at Luton to consider further investment at Luton.
