Do I need to quarantine when transiting through the UAE to the UK from Thailand?

Traveling from Thailand to the UK with a layover in the UAE will necessitate a quarantine upon arrival in the UK, as the UAE is on the red list. Even if you're just changing planes and not exiting the transit area, quarantine is still required. Entering Thailand from the UAE is permissible, but expect a 15-night quarantine in Bangkok or the option to enter under the Phuket sandbox scheme if vaccinated, which allows for roaming on the island after a negative COVID test.
