New simplified travel rules have come into force in the UK, with the traffic light system replaced by a single red list.
Most fully vaccinated travelers arriving from non-red list countries will no longer have to take a test before setting off for the UK.
Airlines UK said it would make travelling abroad easier and cheaper.
But those coming from red list destinations must still pay to quarantine in a hotel for 10 days.
Under the changes, which came into force at 04:00 BST, the green and amber lists have been scrapped.
Testing rules are also being eased for people travelling from non-red list destinations who have been vaccinated in the UK, the EU, the US, or 18 other recognized countries.
Anyone under 18 who is resident in these countries can also travel to the UK without testing.
These groups were already able to avoid self-isolating on their arrival back in the UK.
All travelers – except children under five years old – will still have to pay for a PCR test two days after arrival.
People who are not fully vaccinated will need a pre-departure test and a PCR test on days two and eight after they return, and must self-isolate for 10 days at home.
