With the Foreign Office frequently changing its advice, many holidaymakers will be wondering if their summer vacations are still going ahead.
Last night, it was confirmed travellers arriving in Britain from Belgium, Andorra and The Bahamas will have to quarantine for 14 days from this weekend.
Transport Secretary Grant Shapps said rising Covid-19 infection levels in the three countries mean they have been removed from the so-called travel corridors which meant arrivals were exempt from self-isolating.
So what's the latest from the major airlines flying to European resort destinations? Here's everything we know so far.
Many flights to Portugal are still going ahead by this airline, as revealed on its official website, reports North Wales Live.
This includes from the likes of Liverpool Airport – with flights still available even this week.
And EasyJet are continuing with their scheduled flights to Spain, though package holidays are suspended.
The budget airline has explained that whilst flights will go ahead, customers still have the opportunity to change their booking if they no longer wish to travel.

In a statement, EasyJet said: "We understand that customers may wish to change their travel plans."
Customers who are set to fly within 14 days can transfer their flights without a change fee online.
The airline advised passengers call its contact centre if they would prefer to receive a voucher instead.
Normal terms and conditions apply for flights outside of 14 days – though change fees have been waived.
Additionally, EasyJet has not cancelled travel to Cyprus despite restrictions on the European island.
Jet2 confirmed recently that it had temporarily suspended holidays to mainland Portugal.
This will particularly affect flights to Faro (Algarve), with cancellations in place up to August 17.
The news comes after the airline similarly suspended travel to mainland Spain in recent weeks.
Flights and holidays to the country have been cancelled until at least August 17 – including to destinations such as Malaga, Alicante and Costa de Almeria.
And according to the Independent, suspended flights include those returning to the UK – which had initially been unaffected in an attempt to bring holidaymakers home.
The airline however will contact any affected passengers and offer alternative flight arrangements.
Jet2 has also cancelled its flights to Larnaca and Paphos in Cyprus for the next week or so.
The airline said that flights should resume to these destinations from August 17 – though this is dependent on Cypriot authorities reviewing its entry criteria.
It confirmed that those affected will be offered the option to rebook with no admin fee, a refund credit or a full cash refund.
The budget airline is yet to cancel its flights to mainland Portugal, with many still scheduled.
This includes flights from Manchester Airport that are available throughout August from £16.99.
And Ryanair confirmed last week that it doesn't expect to cancel any flights to Spain this month either.
