Article posted by CAPA on another forum discusses the reallocation of Monarch slots at MAN and BHX. I can't post the link but for MAN it states additional based aircraft from Easyjet(6), Ryanair(3), Jet2(1 extra A330 including some longhaul), a 2 aircraft Vueling base, and a third weekend BA Cityflyer. Plus new (or resumed) services from LOT, Croatian, Air Baltic and Tunisair. Oh and apparently slots also allocated for more unspecified flights from China and India.
Quite how MAG proposes shoe-horn that lot in is unclear ! And as others have rightly said it's only slot filings so plenty of time for it all to shake down before the start of next summer.
