I think the way it's working ATM ( from discussion with friends and extended family in the UK) is that people are still concerned with the risk of their plans being stuffed at the last minute by a local sudden lockdown and/or wider scale control.
Some are getting round this by driving to/from -destination instead of flying gives flexibility and an option to get out of Dodge should it suddenly go wrong...
Some I know are happy to fly short haul, but will book last minute and perhaps might not take an extended break.
What has been clobbered however is any thought at all of booking Long Haul holidays TFN...Danger of being too far out on a limb should things hot up again - they saw how hard it was for people to get home from some parts of the world this Spring. There's also the issue of insurance, especially health coverage, once you get outside of EHIC land.
That sort of thinking is probably a big worry fro those airlines with a significant exposure to the Long Haul market.
