Flying to London from San Diego? Here’s What’s Changing for US Passport Holders
A direct flight from San Diego to London has long been one of the easiest international getaways for Southern Californians. No confusing layovers. No paperwork beyond your passport. Just a long-haul hop and you’re sipping tea in Soho. But that’s about to change—at least for some travelers. The UK’s new ETA requirement is starting to roll out, and while it doesn’t yet apply to American citizens, it’s worth understanding what it is, who it affects, and how quickly the rules are shifting.

What Is the UK ETA and Why Should San Diegans Pay Attention?
ETA stands for Electronic Travel Authorisation. It’s essentially a digital permit that will soon be required for visitors who don’t usually need a visa to enter the United Kingdom. The UK government is slowly phasing it in, starting with a handful of countries, and the plan is to eventually apply it to a wide range of visa-exempt travellers—including, eventually, US passport holders.
For now, Americans can still enter the UK using just a valid passport. If you’re flying out of San Diego International on a Virgin Atlantic or British Airways flight to Heathrow, nothing changes—yet. But this new system is designed to track and pre-screen travellers before they arrive, meaning that even a quick stopover in the UK might one day require additional paperwork.
So while San Diego residents aren’t directly impacted at the moment, it’s only a matter of time before that changes. If you’re planning a trip for 2025 or beyond, keep your ear to the ground.
Who Needs the ETA Right Now—and Who’s Next?
As of now, the UK ETA requirement only applies to travellers from a few specific countries, including Qatar, Bahrain, Kuwait, Oman, Saudi Arabia, and the UAE. These nationals must apply online before travelling, and the permit grants them access to the UK for short stays of up to six months.
The plan is to expand the ETA to all visa-exempt nationalities in the near future. That includes travelers from the US, Canada, Australia, and much of Europe. The UK government hasn’t released firm dates for when American passport holders will be pulled into the program, but it’s expected sometime in 2024 or early 2025.
If you’re a dual passport holder or traveling with someone who holds a passport from a country already under the ETA system, it’s worth double-checking well in advance. Nobody wants to be caught off guard at the gate. And even though you may not need the ETA just yet, knowing the documents needed before you fly will save you from scrambling down the line.
How the ETA Application for UK Travel Actually Works
Let’s say it’s your turn. You’re booking a family trip to Edinburgh next summer, and the new rule kicks in for US passport holders just weeks before you go. What happens next?
The good news is that the ETA is pretty straightforward. You’ll apply online or through an official app. It typically takes just a few minutes, and you’ll need your passport, a photo, and payment for the application fee. Most travellers are approved within a few days—some even within hours.
But don’t wait until the night before your flight. The ETA application for UK travel needs to be submitted before you leave the States. And while it’s rare to be denied, a mistake or delay in your application can derail a trip fast. Think of it as a lighter, faster version of a visa—but still something that can block you from boarding your flight if it isn’t sorted.
One thing to note: the ETA doesn’t replace a visa for those who actually need one. If you’re planning to work, study, or stay longer than six months, this isn’t your route. But for tourists, it’s a quick stamp of approval that gives the UK a better handle on who’s arriving—and when.
Where Do You Get the ETA and What’s the Easiest Way to Apply?
Once the ETA becomes available to US citizens, you’ll be able to apply through the official UK government portal or a reliable third-party platform. And yes, using iVisa is a great way to make the process easier, especially if you’re juggling a group booking or have limited time.
While it’s always smart to go through the official channel when possible, trusted travel document services can take the hassle out of the process by walking you through the steps and flagging any issues before they become a problem. Just be wary of sketchy copycat sites and make sure you’re applying through a secure source.
Again, Americans can skip this—for now. But if you’re the kind of person who likes to be one step ahead, it might be worth bookmarking your go-to application page before the rules officially roll in.
Planning a UK Trip from San Diego? Here’s What to Watch
So, should you panic if you’ve already booked your flight to London for later this year? Not at all. But if you’re traveling in 2025 or beyond, start factoring the ETA into your pre-trip checklist. Just like an eTA for Canada or ESTA for the United States, it’s designed to be quick, digital, and relatively painless—as long as you know it’s coming.
Keep an eye on the UK government’s updates, especially if you travel frequently or have plans to hop through multiple countries. The ETA is linked to your passport number and will be valid for multiple trips across two years, so you won’t need to reapply every time.
If your passport expires within that window, you’ll need to apply again with your new document—but that’s standard for most electronic travel authorisations. It’s all about matching up your personal information with your travel history, in a way that speeds up entry rather than slows it down.
And while San Diego International Airport doesn’t offer customs preclearance for the UK, expect that border agents at Heathrow and beyond will soon be working off the ETA database to speed up entry and keep things moving.
Bottom Line
You don’t need an ETA to fly to London from San Diego—yet. But you probably will soon. The system is already live for a few countries and inching toward wider implementation. Getting familiar with the process now means you won’t get blindsided when it’s your turn to apply. The UK is still as open and welcoming as ever—you just might need a few extra clicks before crossing the pond.
