What about the following scenario?

A. Home – XXX
B. XXX – Home

and, nested within this trip, on a separate ticket:

C. XXX – Home
D. Home – XXX

I’m using all the segments.

This seems to be a classic “nesting” situation, BUT, all coupons in both tickets are being used. (For those not familiar with nesting, the above scenario has the advantage of allowing two tickets with Saturday-night stays, but actually allowing you to be home over the weekend. The actual order in which coupons are used would be ACDB.)

Have done this on two different carriers without a problem. Would it be possible to do it all on UA?
