If you were faced with a choice due to budget constraints:
Option 1: Fly direct in WT+
Option 2: Fly to a nearby point in CW using UUA and then connect onto a BA partner after a couple-of-hours' wait
Fares for both options are more-or-less the same.
Which would you choose in each of the following cases?!
Case 1: Your itinerary involves a choice of day flights to the US west coast
Case 2: Your itinerary involves a choice of overnight flights to the Far East
