I'll be arriving at INV on a Friday at 11:35am (BA from LHR). I am looking at a separate ticket for a flight departing at 13:20 to Amsterdam. I will need to clear immigration, get my bag, and check in again. Assuming the 11:35 flight arrives reasonably on time is this sufficient to make the 13:20 flight? I am originating in the US and must check a bag otherwise I would get off at LHR and just skip the INV flight. Thanks.
