Bus to Mexico City Airport?

[DonJuane]

I believe both ETN and Primera Plus go to the Mexico Norte bus station. I see ETN has a 4:40A arriving at 10A and a 7:40A arriving at 13:00. From there you can take a cab or the subway to the airport. I am cutting and pasting instructions FROM the Airport TO the bus station from a letter I sent my sister. You should reverse the direction of course going the opposite way:

Airport to Bus Station (reverse for the reverse route) (Forgive I don't have time to write this in reverse order but surely you can figure it out - googling the subway map while you read it can help.)

To get to the subway from the airport, walk down to the end of the International terminal, (past Krispy Kreem LOL), counting down gate numbers high to low on the ground floor and on past gate 1 and once you pass the final gate 1, you will be outside. Now once outside you keep walking outside around a tall curved white wall and when you reach the end of the tall white curved wall, then you turn to the left beside the fence and you then walk down the stairs into the subway. You will be at "Terminal Aerea" on Line 5 (yellow). From here you will head north, staying on the single line 5 yellow to reach the “Autobusses del Norte” (bus station), also on Line 5 (yellow).

As you first enter the subway at the airport you will buy a card with credits (only 1 needed). You will be right on the top of the line you want (yellow Line 5). If you wonder which direction to head, the end of the line name (last time I was there it was Politecnico) and hop on the train that direction. Note that some trains will have the last 2 cars reserved for women and children (or is it the front 2?). Now hop aboard the yellow Line 5 and the stops to count off will be the Oceana, Aragon, Eduardo Molina, Consulado, Valle Gomez, La Raxa and then get off (still on the yellow line) at “Autobusses del Norte”. Back above the ground you will see the bus terminal across a large parking lot. Now go find the ETN or bus you have chosen.
