Well, I just booked an interesting itinerary with all this info (thanks!):
LAX-PHL-MAN on US with Envoy Upgrade.
MAN-CPH (arnk) ARN-LHR on SAS
LHR-JFK-LAX on UA with Business Upgrade
total: $1200.
Not bad for June travel! I wanted the eastbound to be in the more comfortable seat. And I truly hope the miles will count towards elite on UA (please!!!!!!).
My only worry is the PHL connection. ITN shows that the LAX-PHL flight is 30% on time. I have a 1 1/2 hour connection. Should be ok, but you can never tell.
