Hi all - just wondering if it's possible for me to check in for a BA flight at LHR T5 7-8 hours pre departure? E.g. at 7-8am for a flight departing at 3.30pm? I know I can do OLCI at T-24 hours but I need to check baggage too.

I think this is possible, but some airlines only allow check in from 3 hours prior to departure, so hopefully someone can confirm if this is doable with BA.
