Looking forward to next summer, although particularly in the current times that can be precarious, it's perhaps worth noting there's double daily rotations on the LGW on 4 out of 7 days per week, perhaps not totally business friendly timings but they are there and let's be honest U2 will be more than happy to fill in the gaps if the demand is there. No sign of LTN.
In the end U2 are a business, if it suits them and their needs they will roll out more/less flights and tweak timings, but the demand for business travel simply isn't there like it used to be. Flying BHD-LHR early in the morning recently not one suit to be seen, this would have been packed with them pre-covid.
I understand the want of flexible schedules etc but the other way to look at it is without them nobody would be flying between London and IOM currently, if the demand was there another carrier would be in making hay selling day returns to business pax and possibly making it unviable for U2 to operate as they do or change timings.
