Confirm the zone with the driver before departure.

Hobby (HOU) vs Intercontinental (IAH) — which to fly into?+

HOU (Hobby): 16 km from Downtown (15-30 min, USD 25-40 cab), mainly Southwest Airlines + some Spirit/Allegiant, closer + faster + cheaper transfer. IAH (Intercontinental): 36 km from Downtown (25-55 min, USD 30 flat), all international long-haul + United hub + most domestic carriers. For Downtown-focused trips: HOU is dramatically more convenient if your airline serves it. For international or non-Southwest carriers: IAH required.

Uber from IAH — how does pickup work?+

IAH ride-share pickup is at the curbside Lane 4 of each terminal's lower-level (arrivals) — clearly signed. No need to walk to a separate lot like LAX. Wait time typically 3-10 min off-peak, can hit 15-25 min during Astros home games (Minute Maid Park) or Texans games (NRG Stadium) when surge spikes 1.8-2.5×. Uber to Downtown: USD 30-50 typical. To Galleria: USD 45-65.

IAH METRO 102 Express bus — practical?+

METRO 102 Express runs IAH → Downtown Houston (RUH/SDH transit center) via I-45 in 40-55 min for USD 4.50. Every 30 min, 04:30-22:30. For solo travellers + Downtown hotels: extraordinary value (vs USD 30 flat cab). Catch: bus stops at the regular METRO Park & Ride station, not directly at hotels. From RUH transit center: short walk or USD 5 ride-share to hotel. Best for budget travel with carry-on only.

IAH terminal connections — domestic to international?+

IAH has 5 terminals (A, B, C, D, E) connected by Skyway people-mover (departures level) + Subway underground train (arrivals level). Terminal E is dedicated to United international long-haul. Connections: same terminal United → United often 45 min. International → domestic (E → A/B/C): allow 90 min for re-check + Skyway. Free shuttle between all terminals + remote parking.

Galleria / Memorial from IAH?+

Galleria (upscale shopping district): IAH flat-rate Zone 2 = USD 50, 30-50 min. Uber: USD 40-60. Memorial (residential corporate area west of Galleria): same zone = USD 50, 35-55 min. METRO bus: requires transfer at Downtown — slow. For business travellers heading to Galleria offices (Marathon Oil, BBVA Compass): pre-book transfer or take direct IAH taxi at the flat rate.

Houston traffic — when is worst?+

I-45 north (IAH to Downtown) is consistently congested 06:30-09:00 + 16:00-19:00 weekdays. A normal 25-min off-peak drive hits 45-75 min. The Hardy Toll Road alternate (USD 5-8 toll) shaves 10-20 min off rush-hour times. Pre-booked transfers + Uber Premium typically use Hardy when peak traffic warrants — IAH flat-rate taxi drivers sometimes don't (no toll fee in flat rate).
