Ridiculous - spent 1hr arguing back and forth with the "1K desk" in Houston about modifying an existing award (same city paris, same cabin, just date change) and they insisted that whatever the computer priced was the price - both agent and supervisor. Such idiocy! Nasty document left in record, though I was polite, but thankfully no problem fixing it during my next call (SLC call center). Still more than two hours wasted on the phone because the vindictive IAH Supervisor continued to remove the flights as the SLC Supervisor added them. We played the "simultaneous error" game for 45 minutes, but thankfully the good-natured SLC sup said we'll wait them out...and we did. He even quickly re-issued the ticket as an even exchange to keep her from removing the flights again while he figured out the new taxes.
Not a happy camper.
