"... the longer these wild handbrake turns in policy go on, the less travel companies, airlines, operators and hotels there will be? It won't be a case of 'holding on for next year' - the options for reasonably priced travel just will not exist next year. There won't be multiple flights a day from your local airport, or accommodation to suit all budgets, or tour providers or transfer operators. There won't be restaurants or bars or attractions to enjoy in places that rely heavily on tourism.
Just being honest and decisive and closing everything until 2022 / 2023 with proper industry support might save some businesses who could then hunker down and mothball themselves to a degree, but to keep us in a constant cycle of hope and despair, sales and then refunds, paying for marketing and then having to pull it, buying in stock and then watching it rot, hiring staff and then laying them off, scheduling routes and then cancelling them, getting dormant aircraft ready to fly and then not going (and many other knock on effects) is destroying the travel industry beyond all repair.
^This. In bucketfuls.
Enjoy your camping in Skegness, and get yourself some decent camping kit because the travel industry is sinking. You'll be going on holiday at home for years if there is no travel industry left, or what there is is too expensive for the average family.
My airline is scrapping aircraft - sending them to the desert to break them up. 35 of them in the last year. Those aircraft won't be coming back. The pilots who flew them are grounded and will need considerable retraining onto other fleets (which don't have any need for them currently) before they are able to fly again, if they ever fly again. The airlines are spending millions getting pilots and planes back ready to fly, only for the government to change the goalposts again after a couple of weeks. There has been no aid to the UK aviation sector, but other countries have funded the long-term standing down of their airlines with government aid. When the world starts going on holiday again, it will be with foreign airlines because by their 'handbrake turns' on policy (great way of describing it) the UK government is killing it's own aviation industry.
But hey, stay safe, and let's hope there's something left when the dust settles, eh?
