Heathrow's Terminal 1 appears relatively peaceful today.
But it's the other end of the Easter break that officials are worried about - will our border controls cope with the influx of travellers coming back in to the country?
"What we need to do is balance the issues of security with the issue of the convenience for passengers," says Labour's Keith Vaz, Chairman of the Home Affairs Select Committee.
"Not addressed, this dangerous cocktail could be a severe embarrassment to the Government. I hope the Home Secretary will take this warning."
Here's a snapshot of Heathrow T5 arrivals recently: bad for UK passport holders; much, much worse for others.
Shadow immigration minister Chris Bryant said: "It is time that the Home Secretary came clean about the security at our borders.
"Her cuts to staff have seen passport queues lengthen, not only leading to delays for passengers but also leaving UK Border Force staff with a difficult decision of whether to relax security to alleviate congestion and risk allowing people to enter the UK without being properly checked.
"With a cut of over 5,000 staff promised by the next election, the Home Secretary is leaving our borders dangerously understaffed, just when the UK is expecting record numbers of arrivals for London 2012."
A Border Force spokeswoman said: "We will not compromise border security, but we always aim to keep disruption to a minimum by using our staff flexibly to meet demand.
"Carrying out full checks at airports help us stop threats from terrorists, criminals and others who want to harm the UK, and make sure that only those with the right to enter the UK can do so."
Airlines claim Britain's airports could end up "gridlocked" over Easter because there aren't enough staff. 11 firms, including British Airways and Virgin Airlines, have have written to the Home Secretary warning of disruption to hundreds of thousands of passengers.
The UK Border Agency is under fire for a lack of staff able to carry out full security checks.
Virgin Airlines said: "After years of reducing frontline staff, returning to a 100% check system will mean lengthy queues at UK airports over critical holiday periods... If the Government wishes to continue with this policy, it must put the resource in place to make it possible."
