Officials warn airports could face five-hour queues at the border when UK opens up to the US and EU on Monday as they call for vaccine checks to be done 'upstream' to save Border Force
- Officials said staff should expect the staggering waiting times during peak hours
- Border Force union warned of more queuing if they have to check vaccine status
- But the Department for Transport said travellers would be checked before flying
Airports could face five-hour queues when Britain opens up to the US and most of the EU next week, ministers have been warned.
Officials said staff should expect the staggering waiting times during peak hours after international travel restrictions are relaxed on Monday.
They called for vaccine checks to be done 'upstream' - at the border before people fly - to help out airport workers in the UK.
The Border Force union said there will be more queuing for passengers if they have to check the jab status of arrivals but did not think it would be 'catastrophic'.
But the Department for Transport last night confirmed to MailOnline travellers would be checked before people fly to Britain.
England will allow US and EU travellers who are fully vaccinated against coronavirus to enter without the need to quarantine from Monday.
Transport Secretary Grant Shapps announced the new rules on Wednesday following intense pressure from the travel sector.
The Scottish Government, Welsh Government and Northern Ireland Assembly followed the move.
But earlier this month the US State Department advised all Americans not to travel to the UK due to the Delta variant and this is not expected to change until August.

UK officials warned ministers before the Covid-Operations committee's move to open up travel it will cause a huge surge in arrivals.
They said it could lead to staggering queues of up to five hours at airports during peak times.
According to the Times, they called for vaccination checks to be done 'upstream' to limit pressure on Border Force workers.
But the enforcement agency's union said they did not think the queues would be 'catastophic' depending on if they had to check vaccine passports.
A spokesman told MailOnline: 'It depends on the traffic. All the resources we have are there but there will still be queues.
'We don't have fewer staff than before the pandemic but they are structured differently.
'There are queues in normal years, that won't be different. If we have to check vaccination certificates, which we're not sure if we will have to, then it will be different.
'The problem has been checking them at the border for the Department for Health.
'There will be more waiting but it will not be catastrophic. It won't be as bad as we have seen during the pandemic if we don't have to check these documents.'
The Department for Transport last night said EU passengers will use an electronic system to show their vaccine status while in the US they have physical copies that will be checked by airlines before departure.
It will help speed up Border Force moving people through British airports when they land.


The UK has a far higher case rate than the US currently - but the countries are on different trajectories
Airlines reported staggering booking surges yesterday, with trips from New York to London spiking by 250 per cent while overall reservations from the US leaped 100 per cent week on week.
There was also a 'swift uptick' in bookings from Portugal, Italy and Greece after quarantine was axed for double-jabbed visitors.
A Virgin Atlantic spokesman told MailOnline: 'Following confirmation that isolation and quarantine for fully vaccinated EU and US citizens arriving into the UK will be removed from 2 August, Virgin Atlantic has seen a significant uptick in interest in travel from the US to the UK.
'Overall flight bookings are up by more than 100 per cent week on week, with bookings from New York to London increasing by nearly 250 per cent, compared to the previous week.'
An easyJet spokesman said: 'Following the announcement, we have seen a positive impact on flight bookings, including on flights between Europe and the UK, now that those who are fully vaccinated and no longer need to quarantine.
'Should passengers wish to move their flights to after the restriction is lifted on Monday, all easyJet customers are able to change their flights this summer without a change fee at any time up to two hours before departure, providing even more last-minute flexibility.'
And flight price expert Gavin Harris, from Skyscanner, said the cost of bookings is staying low as airlines try to entice more customers.
He added: 'Travel providers - including airlines - are using price to help encourage bookings and build confidence as people start to travel again, and this extremely competitive marketplace is fantastic news for travellers looking for good value trips.
'Many providers have been vocal about their plans to keep prices as attractive as possible, so if you know how to search and compare there are many amazing deals.
'Travel is returning, with many countries relaxing rules and popular spots in Europe and further afield welcoming travellers once again.
'We expect prices to fluctuate with demand, but generally we will see providers keep fares low as they compete to win back travellers' business as they dust off their suitcases and return to the skies.'

Cabinet ministers agreed to remove self-isolation rules from 4am this Monday for citizens from the US and some parts of the EU.
At this week's meeting, Boris Johnson personally pushed for the new rules, arguing: 'If we don't let travel restart now, when are we going to do it?'
Currently, only people who received their jabs in the UK from the NHS can avoid quarantine when arriving back from amber list countries.
But under the new system, tourists will not have to isolate for ten days upon arrival if they have had a complete course of vaccines approved by the US or EU medical authorities.
The rules will also benefit British expats living in the US or on the Continent.
Transport Secretary Grant Shapps said: 'We're helping reunite people living in the US and European countries with their family and friends in the UK.'
Amber arrivals who have been fully vaccinated in the US and European countries will still be required to complete a pre-departure test, alongside a PCR test on or before day two after arrival.
The current requirement for a test on day eight will be dropped but those vaccinated in the US will also need to provide proof of US residency.
The exception to the plans will be arrivals from France, who will continue to be required to enter quarantine because of the spread of the Beta variant in the country.



But there is growing confidence that France may be taken off the 'amber-plus' list next week.
Travel and tourism bosses hailed the rule change, with Heathrow chief executive John Holland-Kaye saying the Government had made 'the right decision'.
It follows months of criticism ministers have been too slow to restart international travel and tourism, particularly given the UK's successful vaccination rollout.
Mr Holland-Kaye said: 'We will now work with colleagues in the industry to boost UK trade, reunite family and friends and generate billions in new tourist income.'
Sean Doyle, British Airways chief executive, said the move 'will allow us to reunite loved ones and get global Britain back in business'.
Airlines UK, which represents big carriers, said the move would offer 'a lifeline for thousands of businesses reliant on international inbound travel'.
Joss Croft, of trade association UKinbound, said it would 'allow the £28billion inbound tourism sector, which supports over 500,000 jobs across the UK, to finally restart'.
Ministers announced the scheme as part of a goodwill gesture, hoping the US and other EU countries will reciprocate and allow quarantine-free access for Britons.
But at the moment it looks like such a move is unlikely from Washington, which recently said it had no plans to lift advice that US citizens should not travel here.
The new rules apply to the US, the EU, plus countries in the European Free Trade Association and the small states of Andorra, Monaco and the Vatican City.
They will have to have been inoculated with vaccines authorised by the European Medicines Agency, the US Food and Drug Administration or the Swiss vaccination system.
Mr Shapps said: 'We've taken great strides on our journey to reopen international travel and today is another important step forward.
'Whether you are a family reuniting for the first time since the start of the pandemic or a business benefiting from increased trade – this is progress we can all enjoy.
'We will of course continue to be guided by the latest scientific data but thanks to our world-leading domestic vaccination programme, we're able to look to the future and start to rebuild key transatlantic routes with the US while further cementing ties with our European neighbours.'
Health Secretary Sajid Javid said: 'By reopening quarantine-free travel for travellers who have been fully vaccinated in European countries and the USA, we're taking another step on the road to normality which will reunite friends and families and give UK businesses a boost.'
Claire Walker, from the British Chambers of Commerce, said: 'Businesses will also want to see Government do everything it can to... drive down the cost of any tests required for travellers.'
