JMC is offering short breaks during Easter in a move to avoid the huge costs of flying half-empty aircraft.
The operator said the introduction of three-night packages also follows demand from customers seeking more flexible durations.
A variety of deals are available for departures between April 18-30 including three nights in Minorca, six nights in Portugal and 13 nights in Cancun.
JMC product director Alan MacLean said the flexible durations will help improve load factors.
“It is all about maximising the potential of the properties and airline routes,” said MacLean.
“There is no point in a plane returning from Majorca half empty if we can utilise it for short breaks.”
JMC has initially introduced the flexible durations on a trial basis and will extend them if they take off.
“We were told to offer more flexibility in durations and this is precisely what these April breaks offer,” said MacLean.
