This is perhaps of interest to this thread (BBC News item today - 12-May):
On The Beach pulls all summer holidays from sale
In a nutshell (quotes from the above):
"
On The Beach, one of the biggest UK online travel agents, said it won't be selling any holidays for June, July and August due to "continuing uncertainty around international leisure travel"."
"
By contrast, EasyJet and Tui will begin offering holidays to countries classified as amber, despite government advice remaining not to travel for leisure."
And On The Beach again:
"Unlike many of our competitors, we have no interest in selling holidays that are unlikely to happen, as our business model enables us to put customers first, rather than needing to get cash in the door to contribute to high fixed costs, and offering refunds in the form of a voucher when holidays get cancelled."
I've never heard of OTB but the disparity of attitudes does reinforce my opinion that many travel companies/airlines are just desperate to take our money on a wish and a prayer to bolster their cashflow.
Still no idea about going in August, though I think the USA may be a better bet than much of Europe.
