Ah I thought so, your confused.
The outward journey from the uk, yes you can speed up the tests and they are expensive.
We had the ones you posted the link for outward for £120 per person.
But on return now, you have to self isolate for 3 days and get a test upon return, which we cannot do now, because we have to go straight back to work and school.
If there was a rapid test on return with a result in 3-5 hours, for maybe £150 per person then we might think about it.
As I said we can't really come back early, as we want to see both parents near enough equally or it gets funny.
Ah well, people have bigger problems than this, so it is all pretty self indulgent, but not seeing her family for so long now. I feel they have missed out on our daughter growing up from a 9 year old to a 12 year old punky emo girl.
You can test immediately after landing (drive through at the airport as you leave) and get the results the following day (at worst - ours came through in 5 hours) for £69 pp so don’t need 3 days isolation ?
