Excluding 1Ks...

I am sure there are several of 1Ps, 2Ps, 3Ps, and General Members out there asking this question.

Common Scenario:

Booked on UA C or F due to no availability on partners on the dates desired.

Upon research closer to the departure, one finds a space on NH, TG, OZ, SQ (superior C and F products on partner) for a segment or two (long haul).

A: If it's short haul, less than seven hours, stick with what you have.

A: If it's a long haul and you get NH, OZ, TG, or SQ F, then it's worth the change fee.

Again, the answer to the question/scenario will vary from person to person.
