T3 to T5 airside bus without boarding pass
Hi,
I will be arriving from BCN with lands at T3 but need to meet a colleague at the Sofitel. I believe the quickest way to do this would be to take the airside Flight Connections bus to T5 and pass through Immigration there.
I've taken the bus many times for connections and don't recall them checking boarding passes, but this time I really won't have one and wanted to make sure it won't be a problem!
