While ultra-low-cost carriers often operate from Houston Hobby (HOU), you can still find competitive economy fares at IAH by checking both legacy and low-cost airlines.

Airlines add promotional seats during spring shoulder windows; subscribe to airline newsletters and set April-specific fare alerts to be notified of flash sales. Use flexible-date search to capture the lowest-priced economy seats in April.
For international economy flights from George Bush Intercontinental Airport (IAH), arrive at least 2.5 to 3 hours before departure to accommodate check-in, security, and potential immigration lines. Peak holiday periods and weekend evenings can require extra time; use the airport's live security wait times and arrive earlier if traveling with checked bags. Bilateral agreements and TSA PreCheck can shorten wait times if applicable.
Affordable ground transport options from George Bush Intercontinental Airport (IAH) include Metro bus connections, shared shuttles, rideshares (Uber/Lyft), and airport shuttles to major Houston hotels.

Always compare total door-to-door fare when selecting transportation.
The busiest months at George Bush Intercontinental Airport (IAH) are typically December (holiday travel), July (summer travel), and March (spring break), which often drive economy fares higher. Booking during shoulder seasons (late January–February, September–October) can yield cheaper economy seats. Monitor fare calendars and consider midweek travel to beat peak premium pricing.
Arriving at Houston (IAH) FAQs
Arriving at the Cheapest Economy Destination (CHEAP) typically means basic arrival services with a focus on efficient processing to handle high passenger volumes. Expect economy-class passengers to use standard immigration and baggage claim lanes; premium lanes may be sold or reserved separately. Plan for local transport options and check arrival terminal maps in advance to expedite transfers to hotels or nearby major cities like Cancún or Mexico City.
To save money on ground transport after arriving at the Cheapest Economy Destination (CHEAP), pre-book shared shuttles, use official airport buses, or compare rideshare costs upon arrival. Many cheap-destination airports have competitively priced contracted shuttle services to major nearby cities like Cancún, Playa del Carmen, or downtown hubs. Avoid taxi stands that do not display fixed rates and always confirm fares in advance.
Some destinations add arrival taxes, environmental fees, or airport improvement charges that are separate from your economy ticket and commonly collected on arrival or included in the ticket price depending on the carrier. In July, peak-season surcharges are more likely to appear as airlines and airports adjust fees for increased demand. Check destination-specific information and your airline confirmation for any additional arrival-associated fees.
Economy travelers arriving at international cheap destinations usually need a valid passport, any required visas or electronic travel authorizations, and proof of onward travel or accommodation depending on local rules. Health documentation or vaccination records may also be required seasonally, so verify entry requirements for your specific destination before departure from George Bush Intercontinental Airport (IAH). Keep printed and digital copies of important documents.
Customs and immigration wait times at popular cheap destinations can range from 20 minutes to over one hour during peak periods; anticipate longer waits during holiday months like December and July. To expedite arrival, use available e-gates, have forms completed ahead of time, and stay in the correct queue for economy-class passengers. Check live airport wait time dashboards and aim for off-peak arrival hours to reduce processing time.
November often hosts shoulder-season festivals and lower hotel rates in many cheap destinations, such as local cultural events in Mexico City and early-season beach discounts in Cancún. This can make arriving in November attractive for economy travelers seeking value. Research local event calendars and book transfers early to secure the best combined flight+hotel deals.
