Arriving at Houston (IAH) FAQs
Economy Class - Cheapest Fare (ECO) typically refers to a basic economy ticket with the lowest base price and more restrictions on seat selection, changes, and carry-on allowance. When arriving on an ECO ticket, check your airline’s specific baggage and boarding policies to avoid unexpected fees.
Travelers booking the cheapest economy fares often use routes to high-demand leisure hubs such as Cancun, Mexico City, New York, Los Angeles, London (via sale fares), and major regional centers like Austin and Dallas. Budget-conscious flyers may also choose nearby airports for improved deals.
Arrival procedures—immigration, customs, and baggage claim—are the same regardless of fare class, but ECO ticket holders should expect standard processing times and possible extra steps if they checked baggage. To streamline arrival, use automated passport control where available and have documents ready.
In July, maximize value when arriving on a cheapest economy (ECO) ticket by packing light to avoid checked baggage fees and traveling on off-peak times to avoid long lines. Use mobile boarding passes and check your airline’s baggage policy before arrival to minimize surprises at baggage claim or customs.
Upgrades from an ECO ticket upon arrival are usually limited and may not be permitted; most airlines only allow upgrades prior to departure or at the gate. If you need extra flexibility or baggage allowances, contact the airline ahead of travel to purchase an upgrade rather than relying on arrival options.
For long-haul cheapest economy arrivals, search using flexible-date tools, book during sales windows, and compare multi-stop itineraries.
