Ok. thanks. I guess there are no tricks except to give up an hour of my life . Having to call is such a crap shoot. The first person I spoke with was so clueless (Latvia is not in the same continent as Poland!?) that I hung up. 2nd person was super efficient and got it done in 5 minutes and totally worth the additional ~20 minutes I spent on hold.

Unfortunately these are business class tickets, and we don't have enough miles to book a new itinerary and cancel the old. We are taking advantage of the excursion perk, so have a complicated 3-leg/multi-stop itinerary. What we have now is not ideal but ok. Maybe I'll just wait until the date gets closer. I see a lot of saver availability within 2 weeks of travel
