I want to go from Santiago, Chile to Denver. I can save LOTS of money by buying a LATAM ticket Santiago-MEX-Guadalajara and throw away the MEX-Guadalajara portion. It seems like there's little to no risk since the second leg is not LATAM and I'll have to claim my checked luggage for immigration in MEX anyway. I'm not a LATAM frequent flyer.
I'll get an American, United or Southwest ticket from MEX to DEN. Can anyone see a problem with my plan?
