PILs have been exceptionally scared by the whole Covid thing. They did not leave their house/garden between Feb 2020 and Jan 2021, bleaching the shopping, the lot. Both are 75+ and have health issues.
Huge shock to everyone in the family in March this year when FIL booked a holiday overseas with a major package company. Both appeared excited about getting away. As departure has got closer (they go on 3rd May), they have been regretting their decision. Both are still very scared of Covid, and don't like the fact that where they are going will not require mask wearing, sanitising and distancing. They no longer wish to take the holiday, have paid in full, and know that disinclination to travel is not a valid reason to claim on their insurance.
However - they had an email a couple of days ago saying that the flight details had changed. The holiday company has chartered aircraft from a third party, and will be operating the flight using their own staff. It's also a different type of aircraft which PILs argue is less roomy/modern/ventilated. So they want to cancel based on this material change to their holiday.
My gut feeling says no chance, this isn't a substantial change in the holiday. Possibly the tour company might offer a change to a holiday at a later date, or vouchers - but this is not what PILs want as they are just too scared to go on holiday.
What does everyone think are their chances? The money is spent and gone, but obviously they'd prefer not to lose it.
