It means hassle-free holidays to Spain, France and Greece will be back on for millions, all of which are on the amber list.
A source told the e: "Border Force do have to make some technical changes and they had asked for a bit longer to get the new systems in place. But they can see the writing on the wall on this and they have accepted it will be the 19th."
But travellers must take a test before they come back to Britain and another gold standard PCR test on the second day of return.
It is understood those who cannot be jabbed will also be exempt from quarantine - children travelling with double-jabbed parents would swerve the ten-day isolation with extra testing.
Ministers had been warned that delaying the boost for vaccinated holidaymakers would be a body blow to the summer travel season.
Holidays expert Paul Charles said: “It would be pointless introducing it in mid-August as the summer travel season will have been lost almost entirely — along with tens of thousands of jobs.”
Many European countries are also only allowing in Brits who have had both jabs.
Both Portugal and Malta are only welcoming fully-vaccinated Brits, along with France while Spain now requires a negative test, or proof of both jabs, from all UK arrivals.
Brits heading to Cyprus will need to have two Covid tests unless they are fully vaccinated from tomorrow.
However, Germany has recently lifted restrictions for Brits who are fully vaccinated, after initially closing their borders to the UK due to the Delta variant.
While just the Balearic Islands, Malta and Madeira are on the green list as holiday hotspots, it is hoped that more destinations could also be added.
Brits who have had both Covid shots will also be able to zoom through fast-track lanes at Heathrow under blueprints to open up travel to amber list countries without the need to quarantine.
Travellers will be able to digitally upload their vaccination certificates ahead of their flights and be directed to separate queues at the London airport after presenting them on arrival.
It will mean passengers who are fully vaccinated with be able to skip lengthy queues - slashing the time it takes to get through border controls and stamping out congestion.
The scheme will be trialled by British Airways, Virgin and Heathrow following a meeting last week with Downing Street officials.
Healthy Secretary Sajid Javid confirmed earlier this week that double-jabbed Brits will be allowed to skip self-isolation from August 16.
He revealed plans to rip up the mandatory 10-day quarantine for close contacts of positive cases.

People who test positive will still have to self-isolate for 10 days even if they're jabbed, he warned, and close contacts will still be urged to get a gold-standard PCR test to "get certainty" that they're not infected.
Mr Javid also confirmed under-18s - who are not eligible for vaccines - will be able to avoid quarantine if they come into contact with a Covid case.

He also gave further hope for normality, and said school bubbles will end on July 19, giving a major boost to pupils and parents.
Mr Javid told MPs: “On July 19 it is our plan to remove bubbles and to end the requirement for early years settings, schools and colleges to routinely carry out contact tracing”.
