Thousands of holiday plans have been cancelled this year with coronavirus affecting millions of trips abroad.
Now as the aviation industry looks to restart flights, a controversial measure to require mandatory isolation for most people arriving in the UK is set to begin on Monday.
Home Secretary Priti Patel has defended the plan, saying it is“essential” to save lives.
The measures are designed to help prevent a second wave of infection but the travel and aviation sectors has warned it will cause irreparable damage.
We've taken a look at what the quarantine rules will require nearly all arrivals into the UK to do.
What are the quarantine rules in the UK?
Nearly everyone arriving into the UK will be required to to fill in a “contact locator form”, including details on where they will isolate and how they can be contacted.
The form must be completed before travelling and Border Force will carrying out spot checks.
Non-resident nationals who don't complete the form might be refused entry and Border Force also has the power to dish out £100 fines.
Passengers must have a receipt, either printed or on their phone, to prove they have completed the form.
If international travellers can't self isolate in their own accommodation, the government will provide accommodation.
Travellers from the Common Travel Area (Ireland, the Isle of Man and the Channel Islands) will be exempt, unless they travelled there from overseas in the last 14 days.
And people will be able to use public transport to travel to where they will be isolating, although they will be encouraged to use private vehicles instead.
Public Health England will then carry out spot checks to are following the rules, and may inform the police if they suspect people aren't.
Anyone breaching self-isolation could face prosecution or a fine of £1,000.
And foreign nationals who refuse to comply with these public health measures could also be removed from the country, as a last resort.
The measures will be reviewed every three weeks.
It could be relaxed depending on the rate of infection nationally, what measures other countries are putting in place.
And how many cases have been imported into other countries with more relaxed border measures, and the effectiveness of antibody tests.
What can you leave your home for?
The Prime Minister's spokesman has confirmed that people can leave their home - in limited circumstances.
He said: “There will be a limited set of exemptions just as there was during the nationwide lockdown.
“People are to only leave a property in which they are quarantined if they need urgent medical treatment, support from social services, food or medicine, which they cannot get delivered, or get someone else to bring to them.
“They can leave in an emergency, such a fire or to attend a funeral of a close relative.”
Who will be exempt?
1. Road haulage and freight workers
2. Medical and care professionals arriving in the UK to provide essential healthcare
3. Patients travelling to the UK to receive pre-arranged medical treatment
4. Travellers passing through a UK airport, as long as they don't go through border control
5. Anyone arriving from the Republic of Ireland, the Channel Islands, or the Isle of Man (the Common Travel Areas)
6. Seasonal farm workers, as long as they self-isolate on the farm. They're allowed to mix with fellow workers,
7. UK residents who ordinarily travel overseas at least once a week for work
8. Workers with specialist technical skills, such as system operators, then are needed to carry out emergency work
9. Merchant pilots and crew
10. Seamen and masters
11. Postal workers
12. Essential workers for the BBC
12. Diplomats and consulates
What does it mean for your summer holiday?
Sadly, for many people, this is likely to put them off a summer holiday this year.
It could see people being stuck in their homes all the time after two weeks abroad - which isn't an attractive prospect after lockdown rules have been relaxed slightly.
Currently, the FCO still advises against all non-essential international travel abroad.
It's clear that airlines have put their faith in the prospect of the government securing air bridges with other countries soon.
This would allow people to travel between two countries with low virus rates.
Carriers such as easyJet and Ryanair are resuming a large part of their flight schedule as they aim to benefit from the crucial summer season.
But our poor coronavirus record has already been criticised internationally by other governments who are opening their borders to tourists.
Carriers such as easyJet and Ryanair have announced they will scale up their operations from next month as they attempt to save at least part of the crucial summer season.
EasyJet said it would resume flights to almost three quarters of its network by the end of August, operating holiday trips from all its UK airports.
But travel firms have slammed the rules - including Ryanair boss Michael O'Leary, who said: "You can fill your arrival card as Mickey Mouse, 1 Walt Disney Street, London SW22 - and off you go. It's a shambles.
"Home Office, Border Force and police will tell you off the record, it is unimplementable."
Now Home Secretary Priti Patel has said the government are looking at measures that would allow greater freedom in future – including establishing “international travel corridors” with countries that were deemed safe.
“These measures are backed by the science, supported by the public, and essential to save lives,” she said.
“We know they will present difficulties for the tourism industry, but that’s why we have an unprecedented package of support, the most comprehensive in the world, for both employees and businesses.
“But we will all suffer if we get this wrong. That’s why it’s crucial that we introduce these measures now.”
