I am looking at transiting through LHR on two separate award bookings later this year - not yet booked. Etihad J into LHR in the morning(VFF Gold) and BA J in the evening to Barcelona using QFF points (no status). We need to pick up an item 40 minutes from LHR and check it in on our next flight (it cannot be freighted to Spain for us to pick up there and this ends up being a suitable connection for us).
My question is, if we book BA J on points and don't check in prior to arriving at the airport will we be able to fly ahead of time if there is seat availability? and would there be a cost to this? I thought when booking I should allow the longest time between flights to allow for hiccups and know we will have lounge access at LHR but arriving earlier at the hotel in Barcelona would be preferable.
