what is the latest situation?
Yes, this has been often discussed topic with different answer for various airports.
As we have encountered here, totally opposite datapoints are not uncommon.
As a fact, I know that BA used to allow this on BA to BA connection for afternnon BOM departure, overnite at LHR and next day morning departure to JFK. But that was many years ago. In the name of safety, lot of conveninece is lost unnecessarily and this could be one of it. (Just think about it - how id 12 hour overnite layover is different from 14 hour day time layover?)
Plus, in this case, there is change of airline.
Would love to get recent datapoint one way or other or a reference/link to one. Thanks in advance.
