United and USAirways Hoping Delta and American Match Increased Change Fees

United Airlines quietly has increased change fees on domestic and international travel from $150/$250 to $200/$300.  United has yet to inform their "travel partners", the travel agency community of this significantly important change.  In doing so quietly, United may be positioning itself to backtrack in case Delta and American don't go along.

So far, only US Airways matched United, and now both carriers await moves by Delta and American.
It is likely that this increase will be rolled back if these competitors don't match.  Southwest Airlines does not charge change fees and has no plans to initiate a change fee structure.

Updated May 1: Wish granted! Delta and American obliged and matched exactly United's initiative.
