People travelling to the United States are still required to present evidence of a negative Covid test.
Many other countries have now scrapped testing requirements, including the UK and key European destinations.
There are hopes the US could soon follow suit, knocking a chunk off the price of travel.
Here is everything we know, and the full entry requirements for the US explained.
When will Covid testing end for US travel?
At present passengers are required to show a negative Covid-19 test result taken no more than one day before travel. This can be a lateral flow or PCR test. You must use a private provider, rather than a free government-provided test.
However, US airline Delta has said it is confident this requirement could be dropped within weeks.
Delta president Glen Hauenstein told analysts during the company’s first-quarter earnings call on Wednesday: “Hopefully that gets rolled back in the next few weeks. We are hearing good things from Washington.”
The company’s chief legal officer, Peter Carter, added: “We are getting a strong indication that pre-departure testing will be phased out in the near future, which is quite encouraging.”
What are the US entry requirements?
You will need to get a visa or an Electronic System for Travel Authorisation (Esta) visa waiver to enter the US.
People must also be fully vaccinated to travel to the US. Your second dose should have been administered at least 14 days prior to travel. Booster doses are not required. The NHS app is accepted as proof of vaccination.
Everyone must also present evidence of a negative test result, as explained above, or display proof of having recently recovered from Covid-19.
To use proof of a recent infection in lieu of testing you must have proof of a positive test result taken in the past 90 days and a signed letter from a licensed healthcare provider or public health official that states you have been cleared for travel according to CDC’s travel guidance.
All arrivals must complete a Passenger Disclosure and Attestation form when travelling by air from the UK. This can be completed up to 24 hours before travel and should be done before boarding.
Children under two years old do not need to test to enter the USA. Children under the age of 18 do not need to be vaccinated to enter the country, but unvaccinated under-18s must take a test three to five days after arrival. All children, except US citizens aged undertwo2, must complete the same Passenger Disclosure form as adult.
