1.Pegasus hold slots for SAW still ,so very possible next year.
2.PLAY put in for slots this year and withdrew then so another possible one.
3.Singapore Airlines, very unlikely until they max out Manchester.
4.Cathay Pacific..ditto to SQ.
5.Air Transat YYZ never say never.
6.SAS/Norwegian Oslo.
7.Finnair..one day hopefully.
8.A US carrier to NY.Once AA and 9.United get A321XLRs the economics might work.
10.Hainan to Beijing.
Numbers 3, 4, 8 and 10 are complete fantasies at this current moment in time. Hainan to Beijing seems the least unlikely, however they will be more inclined to increase MAN back to daily
As for number 8, the best shot for that is JetBlue although there is no mention of BHX anywhere on their "wishlist" of transatlantic destinations. JFK-GLA and JFK-MAN will, if they stick to their plans, be the next additions in the UK
6. Aer Lingus UK. Would love to see a long haul carrier based at BHX.
EIUK was launched as practically a BA low-cost division - following the collapse of TCX, BA mulled basing a few Dreamliners up in Manchester to counter the inevitable Virgin expansion. This then turned into Aer Lingus doing core TATL routes BOS, BGI, JFK, MCO.
Realistically, EIUK are committed to more growth out of MAN. To see them base a couple A321s at BHX and perhaps launch JFK would be amazing, but it simply isn't realistic.
To be honest I don't see EIUK expanding out of Manchester - but if they went somewhere, it'd be Glasgow. GLA like MAN has seen a decimation of specifically US routes in recent years. With that new rumour that Aer Lingus will join Oneworld from 2025, I just can't see BA being happy with them setting up shop at BHX.
