Low-cost airline Flybe may soon be operating out of Heathrow, according to unconfirmed press reports.

A Sunday paper report said the carrier is examining the possibility of taking up UK domestic slots out of London’s main airport – freed up after the closure of bmi in 2011

Flybe, which is Europe’s largest regional carrier, operates from four other London airports—Gatwick, Stansted, City and Southend—but not from the capital’s main international hub

Virgin Atlantic took up most of the slots in 2013 for its Little Red feeder service from Manchester, Edinburgh and Aberdeen, although that service closed after failing to attract sufficient passengers.

But Flybe has dismissed reports as “speculative” and indicated that any agreement with Heathrow is some way off with the high cost of operating out of the airport a major factor.

Flybe said that it “cannot comment on the press speculation this weekend regarding any new slot allocation being considered at London Heathrow. Such decisions lie wholly within the remit of the slot allocator. However, any commercial operation would require attractive charges to be offered by London Heathrow.”
