It'll likely be at least 12 months, most likely considerably longer, before air travel demand in the UK returns to what it was in 2019. In the meantime, the remaining core routes with the greatest chance of profit will all have been carved up by other airlines if they haven't been already.

Yes, lovely little airline to fly on as a passenger, but as a company that lost large quantities of money for years and whose industry is in crisis, it's time to bid it a fond farewell
