Flights from London to Houston: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from London to Houston 
AndreaFlew with United Airlines-Apr 2026
Flight connections can be risky with a 2:45-hour gap. Be aware that the Houston airport is very busy.
WarrenFlew with United Airlines-Jan 2024
The ground transportation situation (Uber, taxis) at International Arrivals (Terminals D/E) is frankly pathetic for a major American city. Way too many people and cars for the allotted space. I would recommend taking the mini-train to another terminal (A,B or C) and getting an Uber there, rather than trying to navigate International.
