There are also dozens of dates where a one-way flight to/from LGW is under £50, and many where it is under £30.
You must realise that we are in a transitional period where travel is slowly starting to happen again, but it'll take time for true levels and patterns of demand, to become established. While that happens, we all have to work within what we have.
It is easy to criticise the IOM Government, but no on here knows what Loganair wanted to operate LHR, and what demand was projected to be, bearing in mind that many onward connections simply aren't available or practical, at present. As a Manx Tax Payer, and regular traveller, I think they've done the right thing. If there is a need for intervention, once demand has returned to something like normal, that might be a different matter.
