I am arriving on a BA flight from Washington to Heathrow early on a Sunday morning. I am travelling up to Manchester 90 minutes later also on BA. Both flights are to and from T5. The problem is that they are booked on separate tickets.
Do you think BA at Washington would check my bags through Heathrow so I won't waste time waiting at customs and rechecking bag? I'm not sure 90 minutes is going to be enough time.
