BiziBB, Thank you for changing it to the Budget Travel.
I have NO connection with Volaris, I'm a costumer leaving near LAX and I travel frequently to MEX.
As posted by Mrp Alert Volaris is a LCC in Mexico and it is starting new international routes and by beginning of next year plans to codeshare with WN.
Also emailkid is right sometimes the taxes are more than the ticket.
But the key with this Airline is to buy ticket ahead of time.
