Phil's instagram must confirm Bogota.

This could just as easily be Mexico, no?
Not that e-a-s-i-l-y! Patterns, materials and colors vary between countries and regions. Those are definitively non-Mexican textiles. Go search for Colombian textiles and see how geometry matches.
There are nine daily flights to Colombia from Mexico City and some more from Cancun, I definitively knew that Colombia was next but I couldn't tell the flight or departure point. All of yesterday's flight went by without any sighting and so did the one from this morning.
The pictures posted on live thread are definitively from MEX T2. At the time they were posted, two flights left for Colombia from T2, both of them from AeroMexico, one to Bogota/El Dorado BOG and one to Medellin MDE and another flight left for Bogota from T1.
If the race has stuck with its rules of using two flights close together, then everything points to Bogota and to these two flights:
Out of T1 MEX-BOG 5:45 p. m. → 11:15 p. m. InterJet 2932 4O/AIJ
Out of T2 MEX-BOG 6:09 p. m. → 11:58 p. m. Aeromexico 0708 AM/AMX
This should put all teams into Bogota by midnight. Both flights are now entering Costa Rican air space.
