Flying Business Class to the UK? You Now Need Approval Before You Board
Just a few years ago, it was possible to choose to travel to London one Tuesday to Thursday by booking your flight ticket and nothing else.
There were no additional procedures, no online clearance process.
That era is finished. Business travelers now have to get pre-approval before they can even board a plane heading to the UK.
The change has turned what used to be a straightforward hop into something that needs a little more planning, especially if you’re the type who books late or changes plans often. Plenty of people still look for business class tickets to London so they can sleep properly on the overnight flight and walk straight into meetings, but the ticket itself is no longer the only thing that matters.
The new requirement is the Electronic Travel Authorisation, usually just called an ETA. It applies to almost everyone who previously entered the UK without a visa. If you’re American, Canadian, Australian, or from most European countries, this is now part of the process.
Forvis Mazars’ 2025 business travel briefing confirms that nearly all visa-exempt visitors, including business travelers, must now obtain a UK Electronic Travel Authorisation before boarding, with carriers checking ETA status prior to check-in.
Airlines are checking it at the desk. No ETA, no boarding. It’s that simple and that rigid.
What this actually means day to day
An ETA is not a visa. It is an electronic authorization linked to your passport. With the ETA, you get a period of validity of two years or until the expiry of your passport, whichever expires first. You may visit any number of times during the period of validity. Business meetings, conferences, client visits, short training sessions – those are all fine. What you cannot do is take paid work for a UK company or keep coming back so often that it starts looking like you’re living there.
Applying is done through the official UK ETA app or the government site. You upload a passport photo, answer a short set of questions, and pay £20. Most people get the approval within a day or two. A few take longer, which is why waiting until the week of travel is a bad idea. Every person on the booking needs their own, kids included. The confirmation is digital and linked to the exact passport you used, so don’t switch documents at the airport.
The part that catches people out
Last-minute trips are the real danger zone. You used to be able to react quickly when a client suddenly needed you in London. Now the ETA has to be sorted first, or the airline will turn you away. Travel managers are adding it to their standard checklists the same way they check passport expiry dates.
Connecting flights can also surprise people. If your itinerary sends you through UK border control during a layover, you need the ETA even if you’re only in the airport for a few hours. Pure airside transit is usually fine, but anything that involves passport control triggers the rule.
Getting back to the actual trip
Once the ETA is done, the focus can shift back to the journey itself. The overnight flight still decides whether you arrive sharp or wrecked. Some travelers continue to prefer a proper lie-flat seat so the time difference doesn’t hit as hard.
Business-Tickets has become one of the quieter options people use when they want that kind of flight without turning the whole process into another admin task.
