Thread: CO ZED Agreements: What next ?

Thanks for the speedy reply. I'l try and give them a call.

AI has ZED agreements with CO, AA, DL and US. I have used only AA until now. My folks will be travelling East Coast to West Coast this June. Don't want them to travel AA LGA-DFW-LAX-SFO. Will rather ask them for LGA-ORD-SFO. The point is AI doesn't have ZED with UA, but has with US and CO, both of which Codeshare extensively on UA ORD-SFO. Can they try that on a CO/US/AA ZED ticket ? I've heard a lot of ppl making onto UA, even with UA not having particular ZED Agreements with some of their airlines.
