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 Guadalajara
Entry requirements for US travellers
US citizens need no visa for tourism in Mexico; keep a record of the entry permission granted on arrival. Guadalajara is a common gateway for travellers with family across Jalisco, Michoacán and the Bajío, and the onward domestic and bus networks from here are excellent.
Best time to go
October to May is dry and mild — Guadalajara's climate is one of the most comfortable in Mexico. The rainy season runs June to September. Fares peak hard around Christmas and Semana Santa, when this route carries very heavy family traffic from California, Illinois and Texas, and the cheapest fare buckets go months in advance.
Airports and arrival
Miguel Hidalgo y Costilla International (GDL) is Mexico's second-busiest airport and the hub for onward flights across western Mexico. It is well outside the city, so allow for the drive.
Baggage
This is one of the heaviest-baggage routes we handle in both directions, and it is where buying allowance in advance rather than at the airport saves the most. Excess-bag pricing at a Mexican check-in desk is punitive.

Houston to Guadalajara — frequently asked questions
Fares on the Houston–Guadalajara 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 We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.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 Miguel Hidalgo y Costilla International (GDL), 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.
