The station manager told all passengers they could choose to take the rescheduled flight (from 920pm to 5pm the following day), take the next qatar-operated flight out to Doha in the am, or get rebooked on other carriers. I chose the last option but it was a nightmare trying to get close enough to the ground staff to even get them to help you (about 200 passengers affected, maybe more).

I searched for my own flights in order to still have time to acclimatize or even just meet the trekking start date and came up with
Sin-dxb-mad (emirates 433 /143)
Mad-lim-cus (lan 2707 /2023)
Which will arrive 3 hours after my originally scheduled arrival.

I wrote all these down on a piece of paper and showed it to the staff together with my boarding passes for qr and itinerary for aa. I also mentioned that aa policies covers reacommodation. (They were doing reacommodation for all the qr flights anyway). She took about fifteen minutes to figure out my flights and ticket them using something called a flight interruption manifest. (This document is not a confirmed ticket though, you still need the carrier to issue your boarding passes.)

I believe they will cover you if you take the initiative to give them all the info they need. They are under too much stress from all the other clueless passengers who are asking them what is the solution for them.
Sorry for the long rambly post, I've been 24 hours without sleep.

TL;DR
Propose your own flights, give them all the documentation. Basically help them to help yourself.
