The pre-departure test requirements for passengers entering England have been removed.
The government has scrapped self-isolation on arrival and has reverted to its previous requirement of a test to be taken within 48 hours of arrival.
The changes will take effect at 4am on Friday, January 7.
Boris Johnson said that travel restrictions were introduced to slow the arrival of the omicron variant. Omicron is so prevalent that it is having limited impact on the growth of cases while posing significant costs to the travel industry.
He said that the measures were balanced and proportional to make sure we could live with Covid without letting our guard down. The biggest and fastest booster campaign in Europe is what makes this possible.
Pre-departure tests were reintroduced in December in order to stop the spread of the Omicron variant of Covid-19.
The government placed a number of African countries on its international travel red list, but they were all removed on December 14 when Omicron had community transmission in the UK.
Plan B measures include working from home if possible.
Henry Smith, chair of the all party parliamentary group for the future of aviation, said that the reduction in international travel Covid testing restrictions is a very welcome step forward.
It is essential that the government works with industry to come up with a long-term plan which will help these vital industries begin their road to recovery.
The restrictions have caused unnecessary damage to the whole travel sector, said Clive Wratten, the chief executive of the Business Travel Association.
He said that the government needs to back up these measures with a plan for future versions that don't mean closing our borders.
The removal of all the temporary travel restrictions is a welcome recognition that they no longer serve a purpose.
The UK government has followed the same approach as other European countries in recent days. A continued four-nation approach to travel in the UK should now be possible.
Despite the removal of the temporary measures, airports are still facing a difficult period. There are countries who have imposed restrictions on UK arrivals and consumer confidence has been knocked during the crucial Christmas booking period.
The UK and the devolved governments should set out how they will support aviation to ensure the UK has the airports necessary for our economic recovery.
The relaxation of travel restrictions is positive for the travel industry and will boost confidence at what is traditionally the busiest booking period of the year, according to the chief executive of the Advantage Travel Partnership.
She said that members are currently trading on average at 50% of the year's levels, and that they are beginning to see demand come through.
The impact of the Pandemic has had on the travel industry and people need to see a consistent approach from government in terms of the future relaxation of rules given our highly-vaccinated population.
If the consumer can rely on less confusing government intervention, a continuation of a more flexible approach from travel suppliers, and the expertise of a human travel agent to help guide them through the booking process from take-off to landing, travel will remain ever complex this year.
