Might be something to do with the eye wateringly high fares. I looked at BHX-GIB return with Eastern and even including petrol and parking, about 50% cheaper to fly from MAN with EZY return.
Then I looked at accommodation and thats where my holiday planning stopped, hoteliers there are certainly taking advantage of being on the UK green list!! Having visited a few times in the past, I'm not willing to pay a small fortune to visit again!
