Many thanks for prompt reply and useful info.. That's what I love about FT..
On your recommendation, I have booked on Aeromar leaving at 1840 which is perfect, plenty of time for transfer. Cost great too - around US$100 one way. Return flight doesn't work, but I'll figure out a way back to Mexico City once I get there. It's not that far - around 250 miles.
Much appreciated
