Would I be able to travel to UK via "green list" country to avoid any quarantine in UK?

At this point in time NO ONE has any soli answers for you. The rules are in flux and really just developing. If you want to travel this summer you need to stay loose, be open to change, and not be on a tight budget (be able to afford changes that may arise).

Overview
If you’re travelling to England, what you need to do depends on where you have been in the 10 days before you arrive. If you have been in a country or territory on the:
green list - you must take a coronavirus (COVID-19) test on or before day 2
amber list - you must quarantine in the place you’re staying and take 2 COVID-19 tests
red list - you must quarantine in a hotel and take 2 COVID-19 tests
You cannot currently enter the UK if you’ve been in or through a country on the red list unless you’re British, Irish or you have the right to live in the UK.
You must follow these rules even if you have been vaccinated.

I did not read through all of the details, but your answer may be there

onefastbob- I am flexible when it comes to travel. I thought the vaccines would be the instant game changer in lifting travel restrictions but I was wrong. Worse case scenario I take train or fly to London from France(an amber country) and serve the 10 days that I hope will be cut short to 5 days with a negative test.

joe32F- No specific mention of citizenship. I dont know how much citizenship matters though.

that's a good idea but you should study the rule and regulation of uk on covid to avoid in convince

You wouldn’t have to quarantine after 10 days in a green country, but you will still have to pay for quarantine tests before coming here and on day 2. Things may change over time.

Paris is currently a high risk area, subject to ongoing restrictions and there is a chance that Portugal or whichever green country you choose may ban flights from there. If rates rise in the green country, the U.K. may change its status. The USA may become a green country. The joys of travelling in uncertain times!

Ah, the irony of trying to avoid quarantining at your destination by essentially quarantining in another country.....

As the others have said, no one can give you a definite answer. Particularly with the UK, rules can change fairly quickly. Just ask the thousands of folks who traveled between lockdowns, and how when they left the UK they thought they were fine until the rules changed while they were abroad.

Have a look at the current Green List countries. Many of them (Falklands, South Georgia, St Helens, etc) are far-flung islands. Many of those that arent (Australia, New Zealand, Singapore, etc) arent open to anyone at the minute.

Now, the countries on the Green List are to be updated - but countries could easily be taken off (say, Portugal - which many Brits love) as could be added on (say, USA, which many Brits love).

Finally, please also remember that each of the countries on the Green List have their own entry/exit requirements. Just because France opens doesnt mean you can automatically transit/fly to Portugal, Iceland, or Gibraltar.

Not trying to be a downer or dampen your enthusiasm, I'm just trying to make sure your expectations are realistic.

I would say that the answer is a "Definite Maybe", unless it is not, then it is "probably", until next week, when it will be "Certainly possible, in some circumstances". That is of course precluding a change.

But seriously, too much flux to be certain. About all you can do is plan, take it one step at a time, be very flexible, willing to change plans at a moments notice.

If you want certainty that you will not be stuck in a hotel near an airport for a week or so, or your plans will completely change...then simply wait until the waters clear a bit.

as far as i am aware at the moment you can only enter the UK for legitimate business reasons and not for tourism.If you are coming for Tourism this may indeed change by the time you want to visit .
BUT................... the UK tourism and hospitality sector is just starting to open up again (ie yesterday) and are very restricted in what they can offer ,numbers are very restricted and restaurants bars etc working on 50% or less capacity. Bookings are needed to just about go anywhere especially Historical sites.even my local pubs and restaurants require bookingsand even if you can get a booking (bloody difficult i can tell you) then you may be limited to a 90 minute or 2 hour slot. queues are very likely at many shops and the crazy queues i have seen at some fast food outlets are mental .You will have to download various apps to allow you to enter places ,I have to use Check in Scotland and NHS app ,you may also have to download specific restaurants and bar apps to allow you to order food and drink.
sriously i would advise again visiting for tourism until much later in the summer and even then i would think about it very carefully.

Tom- I would spent 10 days in a green list country where I don't have to quarantine.
If things are too unstable in Europe, I will simply cancel a couple days before I am scheduled to leave(very glad airlines are flexible). I have doubts about the vaccine being the game changer the media hypes its out to be.

above advise is good and to the point.

You don't say when you intend this trip. You are only mentioning the 9th June to identify the potential opening of France, isn't that right?

I ask because the original date for Step Four in England, when most restrictions in England were to have ended, was to have been no earlier than 21 June, 2021. There is currently a strong push to move that date back significantly because of the huge upsurge here in infection, generally in the younger age range, because of the new "variant of concern" - tripled in one week. This is in compliance with the new Webmaster Directive.

If you share your travel date we can give you what the projection may be here (and in France from folks there).

The only two European Green List countries for England for the next 3 weeks - although they could be downgraded at any time with no notice - are Portugal and Gibraltar. Spain, adjacent to both, is most definitely not on the list. So 10 days in Gibraltar would probably get old after the first half day, so it really only leaves Portugal as your one choice for your end run.

Nigel- I intend to be flexible. I am allowed to cancel my flight before it leaves for a full flight credit but to be safe I would cancel the day before if the situation in Europe is unstable. I planned to stay in Europe from June 9th to July 13th. This can obviously change and I currently plan on france and UK only at the moment with a green list country in between to avoid quarantining in UK.

phambrent - yes, I understood that is what you intended. But as Nigel says, currently, your only green list options in Europe are Gib and Portugal. Your only other options are far-flung islands or places that arent accepting visitors. I am just cautioning you that every country on the green list has their own entry requirements (which can change), and can be removed from the green list pretty much at the whim of the UK government.

Also keep in mind, green list or not, you'll still have a testing requirement.

Good luck in your travels.

joe32F- No specific mention of citizenship.

It absolutely mentions citizenship:

You cannot currently enter the UK if you’ve been in or through a country on the red list unless you’re British, Irish or you have the right to live in the UK.

. I dont know how much citizenship matters though.

It doesn't matter at all (unless you are a UK or Irish citizen, or have a long-term resident visa as stated above). It matters where you have been physically present.

Before you travel to England from a green country you must:
take a COVID-19 test
book and pay for day 2 COVID-19 test – to be taken after arrival in England
complete a passenger locator form.

Portugal has just been removed from the list of green countries for the U.K. so this is no longer an option.

Jennifer- I read about that. Pretty crazy but not surprising. I have overestimated the positive effect the vaccine would have on reopening. I will cancel my trip to Paris to tonight and fly to UK in three weeks instead. So much volatility in the travel situation that I didn't think would be there. There must be something about the vaccine the public is not being told about.

Many people in virtually every country in the world are not fully vaccinated. As more variants crop up that turn out to be more contagious than the original virus, countries are getting cautious. There's been recent information published to the effect that a single vaccination (of one of the two-dose vaccines) isn't equally protective against all the variants. That is probably affecting the UK's decision-making in particular, because it has a very large number of people with just their first vaccination.

WSJ today reporting that US is still on the amber list, so 10 day quarantine.

I also read elsewhere the some people are transiting through Ireland to try and "greenwash" their point of origin, but all someone has to do is see your passport cover ...

Phred- people are transiting through Ireland because of cheap airfares not "greenwashing". Someone has to be in Ireland for 10 days to enter uk without quarantining. There is a 14 day quarantine for all travelers who enter Ireland.

Sorry, but you are naive if you think that a fully vaccinated person should be allowed to travel without restrictions. You still stand a risk of spreading or catching Covid, albeit at a lesser level.

The U.K. is being severely impacted by the Indian variant and we don’t yet know if the vaccines protect against this variant. Over half the U.K. population has now had both vaccines, yet infection rates have tripled in a week and hospital admissions are rising again.

International travel is being restricted for Brits to try to avoid yet another lockdown. We also don’t want to see international visitors coming here if it leads to more domestic restrictions. Sorry, but that’s the view of most people that I have spoken to about the topic.

I called British Airways - my choice for International - The representative told me as long as I'm only "transiting" - Boston - LHR - (2 or 3 hour stopover) - FCO, I don't need to quarantine. Staying in London or similar, I would need to quarantine. Things could change in a month or so.

P.S. I don't intend to travel abroad this year. I was curious what the current protocol is.

Does anyone have an idea when or if the UK intends to review the various statuses (Green/Amber) and rules for visiting? I have relatives I had hoped to visit on way back from Greece to US, beginning July, at first I thought they were going to revisit everything by June 21 but English relatives seem to think that is unlikely. Previous to May 17 changes UK listed countries that would move to green/amber list on those dates.
