C-W-S, thanks for mentioning that changing the final destination from INV to GLA might be a feasible option. I never even considered that. The question is, should I book a £50 one way economy ticket to Glasgow now. Or take the risk that changing the booking after departure will be affordable; and if it is not, how much more expensive would a one way ticket be at that point?
For your first point above, then so long as your boarding pass is not scanned in T5 then that is all you need to do, at 30 minutes to departure approx, the system knows you are not going to show up.
For the second point, if you haven't already travelled then I would book an Avios ticket which could be cancelled at 24 hours with the loss only of the the RFS fee (£17.50 assuming it is a single). Otherwise you need to have a fairly forensic knowledge of ticketing to work out which ticketing route is the most viable.
Note that if you have checked baggage, you may not have a choice, your bag will almost certainly be tagged to INV. It can be reclaimed in LHR but it's hassle and I wouldn't recommend it. If you are actually arriving in T3 it gets even more problematic. If HBO then there isn't this difficulty.
