Ryanair:
It would seem MAN is losing 19 departures a week over the winter with the latest cancellations. How the original schedules for winter 17/18 compared to last winter I'm not sure.
The cancellations are frequency reductions on predominantly "city" type routes.
For example, CRL, BCN, and BGY are losing flights on some days when there were second rotations. However, HAM is reduced to 3 x weekly instead of daily and there are weekly frequency reductions to Madrid, Rome and 2 weekly services to Lisbon.
It's disappointing, especially as LPL & LBA appear to have no cancellations and BHX only the odd DUB rotation. I don't know exactly how many weekly departures Ryanair were originally scheduling from MAN this winter but I would guess 19 represents at least 7%, possibly more, and something like 150,000 seats from Nov to 24 March.
