Houston is a United fortress hub and the energy capital's gateway to the world — €49 to Atlanta, cheap Central American and Caribbean escapes, and a direct transatlantic hop to London from the heart of Texas.
George Bush Intercontinental (IAH) is far north of the city, and the budget link is the METRO 102 bus from Terminal C to downtown — about $1.25 (cash only, no change given), every 15–30 minutes, taking 50–90 minutes depending on traffic. For a faster, more comfortable ride there’s the Route 500 Downtown Direct express at $4.50, running from four downtown points to Terminal E every 15–30 minutes. Most visitors rent a car given Houston’s sprawl, but for a straight downtown trip on a budget, the 102 works; for speed, pay the extra for the 500.
As a base, Houston’s value is United’s enormous network. Latin America and the Caribbean are densely served and cheap, and the European routes give Texas a direct transatlantic reach.
Cheap and close: domestic and Central America
Start with the steals. Atlanta (€49) is a remarkably cheap domestic hop to the Southeast’s biggest hub. Then south: El Salvador (€224) and the Bahamas (€244) are strong winter-escape fares. These are the impulse routes — close, cheap and the obvious way to swap a Texas summer or a grey winter for sunshine, with United’s dense network keeping fares competitive.
South America — Houston's strength
Houston is one of the best US gateways to the northern half of South America. Medellín (€389) reaches Colombia’s city of eternal spring, and Guayaquil (€392) opens Ecuador — and the gateway to the Galápagos. United runs these heavily, so award space and sale fares appear more often than on routes with a single carrier. If the Andes or the Pacific coast of South America is your target, Houston is a logical, well-priced launch point.
The transatlantic hop
One route crosses the Atlantic directly: London (€539) — the classic gateway to Britain and onward across Europe, nonstop from the heart of Texas. For travellers heading to Europe from the south-central US, a direct transatlantic fare that skips a coastal connection saves real time. It’s the longest route on this board and the bridge to a whole continent.
A note on these US-origin fares
These are leisure round-trips at their lowest verified levels and swing hard by season. The Central American and Caribbean fares are cheapest in the shoulder weeks around US winter break; the South American routes are best in the shoulder seasons; London is cheapest outside the European summer peak. Because United dominates IAH, watch for its sales — the Latin American and European fares in particular drop noticeably when a promotion runs.
