However the fact that you are seeing 1A available on your flight if you make a dummy booking is cause for concern. I know from experience that DL and LA’s systems do not synch well. I have a trip to LIM that was partially on DL, partially on LA, that I was able to switch to all DL as part of a schedule change. Fully understand you can’t do that BOG-LIM.

If I were you, I’d call back during normal business hours and ask again. Tell them your concern with regards to the seat, and ask them to please check with the JV (joint venture) desk and/or Global Ticketing to make sure all is well. You might have a new LA PNR that isn’t synched right. Best case all is correct. Most likely case is you have a spot on the flight, but you will get a leftover seat and not 1A. Worst case is day of departure LA can’t find your reservation/ticketing issues and you run the risk of missing the flight. Best to try and get ahead of any potential issues now.

Let us know how it turns out.
