Flying out of Houston Intercontinental
Houston Intercontinental is United's Gulf and Latin America hub, and its Middle East service makes it a strong one-stop gateway to South Asia — Gulf carriers connect IAH onward to virtually every Indian and Bangladeshi city through their own hubs. Sugar Land, Katy and Pearland hold one of the largest South Asian populations in the South, and the corridor is competitive enough that consolidator fares out of IAH often beat the published fare from a nominally better-connected coastal airport.
What to know before you fly to Mexico City
Entry requirements for US travellers
No visa is required for US citizens visiting Mexico for tourism. Note the entry permission you are granted on arrival and keep it with your passport. Mexico City sits at about 7,350 feet, which is high enough that the altitude is noticeable on the first day — worth knowing if you land and immediately plan a long day on your feet.
Best time to go
March to May is warm and dry and the most pleasant. The rainy season from June to September brings heavy afternoon downpours rather than all-day rain, and fares drop accordingly. The two sharpest demand peaks are Semana Santa (Holy Week) and mid-December through early January, when diaspora travel fills the aircraft and fares roughly double — those need booking months ahead, not weeks.
Airports and arrival
Benito Juárez International (MEX) is the main airport and is close to the city centre, though the traffic makes that less useful than it sounds. Felipe Ángeles (NLU) is the newer secondary airport well to the north and is a genuinely different trip — check which one a cheap fare uses. Toluca (TLC) is a third option, further out again.
Baggage
Mexican low-cost carriers price bags aggressively and enforce cabin-bag sizing far more strictly than US airlines do. On the VFR routes, where people travel heavy in both directions, the fare with a proper allowance is frequently cheaper in total than the headline bargain.

Houston to Mexico City — frequently asked questions
Fares on the Houston–Mexico City route vary widely by season and how far ahead you book. We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.
Carriers on this route include American, United, Delta, Aeroméxico, Volaris and Viva Aerobus. Others serve it on one-stop itineraries, and the cheapest is not always a name you would expect — the lowest fare we have tracked here was on a carrier outside that list more than once. Itineraries offer nonstop from most US gateways, and total journey time runs about 3–6 hours. Which carrier is cheapest changes with the season and the fare bucket rather than staying fixed, which is why we compare them all on every quote.
Plan on 3–6 hours from George Bush Intercontinental (IAH) to Benito Juárez International (MEX), including time on the ground if your itinerary connects.
Book two to four months ahead, and five or more for Christmas, Semana Santa and US spring break, which are the three peaks that matter on this corridor and the three that sell out first.
Yes — this route has nonstop service, with nonstop from most US gateways. Nonstop is not always the cheapest option: a one-stop itinerary on the same dates is frequently a few hundred dollars less, and on a journey of 3–6 hours that trade is worth pricing rather than assuming. Frequencies change by season, so call us for what is actually flying on your dates.
Bush Intercontinental (IAH) is Houston's international airport; Hobby (HOU) is domestic and largely Southwest. Nearly every long-haul option departs IAH, so the real question here is terminal rather than airport — international departures use Terminal D or E, and the inter-terminal transfer is worth building time for on a tight connection.
Less than on the long-haul routes, and we would rather say so. These corridors are served by low-cost carriers with genuinely competitive headline fares. Where we earn the call is the total: bag fees on these routes routinely exceed the fare gap, seat and change fees are aggressive, and for a family travelling heavy the cheapest advertised ticket is regularly not the cheapest trip. We price the whole thing. SkyKaro's agents are reachable 24/7, and nothing is charged until an agent has confirmed the itinerary and the price with you.
