MEX to IAH
 

Where can I find cheap flights one way from Mexico City to Houston??

Look to fly Feb 17.
$$: as low as possible (<$100 US)

You aren't going to find a flight that cheap. Both Continental and Aeromexico fly nonstop from Mexico City to Houston, but for more like $200.

Check orbitz or expedia.

www.aviacsa.com just found a random OW for $120. US.
The discounters are:
aviacsa
Volaris
interjet
aerolitoral
azteca
avolar
alma de mexico
click
viva aerobus
mangicharters

Thanks for the list of discounters. I see the $120 fare on Aviasca, but it comes out to $175 w/ tax. It's cheaper than the major airlines, but still pricey.

Guess I'm out of luck.

Don't give up.
Just got a bargain $245 US BJX-TIJ RT incl the awful MX taxes.
