I'll get to try all of of the shuttle combinations in October...flying QX SJC-LAX then connecting to DL. Hopping around the east coast for two weeks on business then home on AA JFK-LAX and QX LAX-SJC.
I have more than 2 hours between flights going out so I shouldn't have a problem making the DL connection. I'm a bit more concerned about the return...only 60 minutes between flights.
I'll think good thoughts and if I miss my QX connection on the way back I guess I'll have to wait for the next flight and spend some time in the Boardroom!
