I recently travelled from Singapore to DFW. My original trip was on Cathay from SIN to HKG and then an AA flight from HKG to DFW.

Due to a 2.5hr delay of the original flight, Cathay moved me to a UA flight from SIN to LAX and then AA to DFW. While at the airport, I complained as I would have been stuck in a middle seat and I was concerned about all the EQM miles I would have lost by not flying on AA.

They eventually found an alternate route for me with 3 legs:

1) SIN to HKG on Cathay
2) HKG to LAX on AA
3) LAX to DFW on AA (last flight of that day)

it meant long layovers, but I was satisfied. It should be noted that when I asked them print an itinerary for me, it included these flights AND the previous UA route.

i flew the first two legs but when I got to LAX, I was looking at the AA model app and noticed my LAX-DFW flight disappeared and I saw a new HKG-DFW flight for the next day. Odd as I was already in LAX at the time.

Someone at Cathay had changed my flight plans mid-flight.

I was able to talk to a AA rep and she confirmed that my flights had changed. Luckily she had a seat available on the LAX-DFW flight and was able to put me back on the flight so I can get home, but that incident was very distressing. I could have been stuck in LAX until the next day if there were no seats. My new trip was already adding 12 hrs and being stuck in LAX would have easily added yet another 12 hrs at least.

DoI have any recourse for any sort of compensation? Do I just suck it up and probably never fly Cathay again?

Another question.....if I had taken the original UA would I have had any recourse to get the EQM miles on AA anyway....this leg would have been at least 8,000 EQM miles. I pretty much only fly AA when I can so I can get elite status on them.
