Ok... I have had a question brewing for some time and now I've finally gotten around to post it so here it goes:
Back in May 2004 my wife and I took a trip to Hawaii on Continental. The plane ride to and from was great however on the trip out (according the map) we never flew over the border into Mexico. Once over the Pacific Ocean we went directly over the Channel Islands and then turned South West towards HNL. Apparently avoiding Mexican airpace. On the way back we went directly over Mexico on a strait shot to IAH.
The flight out was on a Tuesday leaving IAH about 2:00 PM and the flight back was a redeye.
I know this is probably a stupid question but I've been itching to ask it but what is usually required in order to fly over Mexican airspace and why the different flight paths?

One of the basic premises of flight planning is to either avoid or maximise the effects of upper level winds depending on if one is travelling with or against them.
As far as flying over Mexico, nothing too odd whatsoever cutting across Mexico or Canada airspace for US air carriers, with only the requirement being the filing of an ATC flight plan with the appropriate ATC enroute facility.
While routings over Mexico might not be as frequent, its a standard occurrence where domestic US flights traverse Canada - particularly those headed to/from the Northeast region often routing via into Canada around the Great Lakes region besides those obvious flights headed to Alaska and back.

Even though not landings in Mexico though, if I recall they do have to pay a tax using Mexican airspace. But the cost of fuel saving on the return leg may or could easily offset this. But I have to agree this may have been more due to upper level winds at the time.
