I'm flying (my first) F in January next year and made a slight mess of my valet parking reservation. I actually booked it for a day earlier than we're flying!

This might end up working in my favour, as we're staying at the Hilton T4 the night before the flight which has a free private shuttle service to T5 and back.

It would cost £16 for a night's parking at the Hilton whereas the extra day's parking I booked at LHR is only about £4, so I was wondering if I could OLCI, then bag drop around 6-7pm the evening before the flight which is at 12:45 the next day, leave the car there and just take the shuttle back to the Hilton.

I called BA gold line to ask about this and was told as I was flying F I could bag drop "at any time before the flight". So I asked, "so the day before is OK?", she replied "at any time before the flight!", so I said "so, a week before is OK?", she replied again "at ANY time before the flight!".

I found this a bit too good to be true so I thought I would ask on here, surely there must be a limit to how far in advance you can bag drop!
