Looking for a bit of reassurance for a complicated situation, largely brought about by me taking a very complex BAEC year end trip to ensure that I finally hit gold

RFS booking (oneway) in place for LHR ABZ for Mrs mcinverness and the 2 youngsters. Mrs mcinverness now probably won't travel, and I will buy a ticket for Granny mcinverness to accompany the kids.

My question - will there be any problem due to Mrs mcinverness not travelling?

I am sure there won't be, but Mrs mcinverness is v nervous about these kind of things, and I will still be in transit from Australia when they travel so won't be able to offer any assistance in the event of problems...

Your collective advice I hope will put my mind at rest.

Thanks!
