The other thing that has been pointed out with Tui and Jet2 when they start operating again is the huge logistical operation in getting staff out to resort especially when you consider some of the Tui/ First choice Family resorts have over 50 UK staff in each hotel.
Normally it would be more staggered with some going out one day and then more the next day using EZY and other low cost carriers
I know some First Choice entertainment staff have been told that they need to be ready to fly from 4th July onwards and that flights would likely be from central location like Gatwick, Birmingham and Manchester and then guests would start arriving a week later.
