The UK's biggest tour operator TUI has confirmed it will be resuming flights and holidays to 19 destinations when non-essential travel from England resumes from Monday.

That includes flights to Portugal and Madeira which are included on the UK Government green list of destinations that are quarantine-free, the Mirror reports.

Both green and amber list destinations are listed by TUI, but it will not operate flights or holidays to resorts stipulating visitors must enter quarantine on arrival. It will not be flying to any red-list countries.

Initially, TUI will offer flights from England airports only - Gatwick, Manchester, Birmingham and Bristol - between May 17 and May 27.

TUI has cancelled all holidays until June 6 to red destinations or trips to amber countries where the UK Foreign Office advises against all-but-essential travel until the same date.

Green List

When returning to the UK you'll need to take a pre-departure test, and a PCR test on day two when you're back.

Amber List

When returning to the UK you'll need to take a pre-departure test. You'll then need to self-isolate at home for 10 days with PCR tests on days two and eight.

However, you can also opt to take a test on day five and if the result is negative, be released from quarantine early.

Whether you're travelling to a green or amber list destination, you'll be required to undertake PCR testing when you're back in the UK.

Some travel companies and airlines have secured discounted tests for their customers. TUI offers testing kits from £20pp for package holidays, while airlines like easyJet and Ryanair have discounted tests for £60 when you book a flight with them.

Meanwhile, Boots has teamed up with MyHealthChecked and is selling at-home PCR tests for £65, which you can buy on boots.com and get delivered to your house. There is also an in-store Covid PCR testing service available for £99 at over 200 of its UK stores, which offers results within 48 hours.
