Not familiar with OSL so a question please. Considering a trip flying LHR-OSL with BA and then OSL-DXB with EK. The BA flight is scheduled to arrive at 1035 and the EK one to leave at 1435. These would be on different bookings/PNRs. That seems a reasonable connection to me but slightly concerned about the apparent need to go through immigration and risk of queues. Any thoughts?
