Flights Ciudad de México → Houston: airlines, fares, timing

Mexico City to Houston is one of the busiest corridors between Mexico and Texas, with around 42 flights a week.

At a little over two hours’ block time it is a short, direct hop done comfortably in a single daytime sector.

Airlines operating this route

Three carriers fly MEX-IAH: Aeroméxico and United Airlines operate full-service, with checked baggage included, while Volaris flies it low-cost, with a leaner base fare to which bags are added. United is based in Houston, giving it the widest network of onward connections across the United States. All three fly direct, so the choice comes down to schedule, included baggage and price.

MXN fares — what to expect

MEX-IAH fares move mostly with the family calendar. The December weeks, Holy Week and the summer are the most expensive and fill early — for those dates, booking two to three months ahead is sensible. Outside the peaks, four to six weeks usually secures a reasonable economy fare in MXN, and the low-cost option is cheapest for travellers packing light.
