Trade unions are worried about the prospect of job losses at Flybe, after the airline put itself up for sale
It's the largest regional carrier in Europe, but has been struggling because of falling demand, and rising costs.
Flybe says it's already in discussions with potential buyers.
Energy FM understands Stobart Group have shown interest in buying the airline.
Stobart Air has operated Flybe routes to and from the Isle of Man for a number of years but that deal ends in March next year.
