Two one-way US-UK awards and customs/immigration
I am a PM. I'm planning an RDU-LHR trip next summer. I'm wanting to go over Business class and back in economy. Can you book that online? I know I can call DL PM and book it by phone with no service charge. If I book online with two one-way awards as is allowed as of 1/1/15, do I get into any trouble at either customs/immigration at either end? (As PM I know I can change/cancel with no service fee)
