I'm wondering about an easy and reasonably safe way to get from Mexico City International Airport (MEX) to downtown.
If good public transport is available, I usually prefer that. And as I noticed there's a metro station (Terminal Aérea) at the airport, that seems like the most obvious choice. However...
An article that's one of the top hits for a relevant search recommends Metrobus (i.e. a type of bus) over metro, citing security considerations:
The Metrobus can be boarded between Puerta 6 and 7 in Terminal One, and Puerta 3, lower level, in Terminal Two. I judge this service to be significantly safer than the metro, and the price is right.
Wikivoyage's airport-to-centre section also warns:
Realize that the Metro has its own risks. Pick-pocketing is a moderate danger here so be aware of your surroundings, and keep an eye on your belongings. Especially, don't take the Metro during rush hour unless you are especially fond of the sensation a sardine has in a tin.
How bad is the metro really? I would carry one largish backpack, and head to the centre between 6-7 o'clock in the morning. I can usually adapt to different surroundings easily and I speak Spanish.
Would it actually be likely that someone tries to steal my stuff, seeing I'm fresh out the airport? Should I play it safe and take the metrobus or maybe a taxi instead?
Besides security, are there other good reasons to prefer metrobus or taxi? (Looking at the metro map, I'd have to change lines at least once.)
Of course, first-hand experiences are especially appreciated.
