BMI have an Airbus A320 based at Manchester all week operating flights to Greece and Turkey for Olympic Holidays and Custom Flights.
Glasgow sees an A320 based until mid July when it moves to Newcastle, again operating for Olympic.
An Airbus A321 is based at Belfast until mid July, it is then based at East Mildands from mid July onwards operating flights around Europe for Thomas Cook.
An A321 is also based at Manchester from mid July operating flights for Teleticket Travel. It operates most of these flights on W services with Gatwick.
Hope this helps!
