There must be a lot of repatriation flights because on flightradar24 there
seem to be just as many flights across europe and the atlantic as ever and
plenty of aircraft around heathrow and gatwick.

Yes, see

[Of course, the many code-shares exaggerate the number of flights, both
those operating and the cancelled ones. ]

As I'm sure you'd said in the past, the flightshares can be easily
ignored, simply by eyeballing flights at the same time, to the same
destination.

The 12:05 to Philadelphia is a doozy.

I suspect, however, that these cancellations are last minute ones,
rather than compared to the timetable they were expecting to be running
a month ago.
