Houston to London is about eight and a half to nine hours with six hours of difference, and the people on it are mostly there for work, usually in energy, usually on a tight schedule.
Bush, not Hobby
Transatlantic flights leave from George Bush Intercontinental, north of the city, not from Hobby. Allow a good hour from downtown in normal traffic and more at rush hour. Check the airport on your ticket the night before, because people do go to the wrong one.
Six hours lets you plan from the office
Mid morning in Houston is late afternoon in London, so you can arrange everything in your own working day. Do it before you fly: the evening you land is the only free one on most of these trips and it is no time to be starting from nothing.
The climate swing
Leaving Houston heat for London weather in the same month is a bigger change than it sounds. Carry a layer you can put on at the airport.
The flight home
Going home takes longer than coming over. Heading west you are flying into the jet stream rather than along it, and on this route that is worth roughly an extra hour in the air. London back to Houston is scheduled accordingly, so read the arrival time rather than assuming it mirrors the flight out. It matters most if you have a connection waiting at the other end.
Before you book
Visitors from the United States who do not need a visa still need an electronic travel authorisation, or ETA, before they fly. It is a short online application, and it should be made through the official GOV.UK ETA service, not a site that charges extra to do it for you. The rules change, so check them before you book.
Worth reading first
The booking guide covers what to say when you make contact, and the rates guide covers what things cost.

Common questions
How long is the flight from Houston to London?
The flight from George Bush Intercontinental takes about 8.5 to 9 hours eastbound. Add the connection time if your fare has a stop, and allow for getting to and through the airport at both ends.
What is the time difference between Houston and London?
London is 6 hours ahead. The United Kingdom and most other countries change their clocks on different dates, so for a few weeks each spring and autumn the gap shifts by an hour.
What time should I message from Houston?
London runs 6 hours ahead of you. Messages sent between about 5am and 5pm your time land during London working hours, which is when replies actually come.
Which London airport do flights from Houston land at?
Most land at Heathrow, about fifteen miles west of central London and on the Piccadilly line and the Elizabeth line. Some services use Gatwick, to the south, so check the airport on your ticket before you book a hotel.
Do I need an ETA to fly from Houston to London?
Most visitors from the United States who do not need a visa need an electronic travel authorisation, or ETA, before they fly. Apply through the official GOV.UK service only, and check the current rules before you book, because they change.
Do I need to arrange things before I fly?
It helps. Good diaries fill days ahead, and arranging from home means you are doing it awake and unhurried instead of jet lagged in an unfamiliar city.
Is escorting legal in the UK?
Yes, in England and Wales it is legal for two consenting adults to exchange sex or company for money. What is illegal is the activity around it, such as soliciting in the street, running a brothel or controlling someone else's work. The Crown Prosecution Service sets this out in its published guidance.
Is prostitution legal in the UK?
Selling and buying sex between consenting adults is not itself a crime in England, Wales or Scotland. Northern Ireland is the exception, where paying for sex has been an offence since 1 June 2015. Public soliciting, brothel keeping and exploiting another person's work are offences in different forms across the UK.
