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 San Salvador
Entry requirements for US travellers
US citizens do not need a visa for tourism in El Salvador; a tourist card is purchased on arrival for a small fee, payable in US dollars — which are also the country's currency, so there is no exchange to worry about. Confirm the current requirement with the Salvadoran consulate before you travel, as the arrangement has changed before.
Best time to go
The dry season runs November to April and is the most reliable time to travel. The rains come May to October, usually as heavy afternoon storms rather than washouts. The two big fare peaks are December and Semana Santa, when Salvadoran-American families travel home in volume from Los Angeles, Houston and Washington DC — those need booking months ahead.
Airports and arrival
El Salvador International (SAL) is about forty-five minutes south of San Salvador, near the coast. It has become a significant regional connecting hub, which is worth knowing: fares onward to the rest of Central America through SAL are often better than routing via Panama or Mexico City.
Baggage
A heavy-baggage corridor in both directions, and one where the carriers know it and price accordingly. Buying allowance in advance rather than at the desk is the single clearest saving we make on this route.

Houston to San Salvador — frequently asked questions
Fares on the Houston–San Salvador 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 We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.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 Avianca, United, American, Delta, Copa Airlines, Volaris El Salvador and Spirit. 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 the main gateways, otherwise one stop via Houston, Miami or Panama City, and total journey time runs about 4–8 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 4–8 hours from George Bush Intercontinental (IAH) to El Salvador International (SAL), including time on the ground if your itinerary connects.
Book three to five months ahead, and considerably further for December and Semana Santa, when family travel fills these routes and the cheapest fare buckets disappear early.
Yes — this route has nonstop service, with nonstop from the main gateways, otherwise one stop via Houston, Miami or Panama City. 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 4–8 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.
Often, yes. These are consolidator-rich corridors where the published fare and the wholesale fare diverge, particularly around the December and Semana Santa peaks when the cheap public buckets vanish months ahead. Agents can also reach inventory on regional carriers that US booking sites either do not display or display badly. SkyKaro's agents are reachable 24/7, and nothing is charged until an agent has confirmed the itinerary and the price with you.
