The UK's largest airport, Heathrow, is to extend a cap on the number of passengers flying from the airport until the end of October due to staff shortages.
The BBC reports this means the limit will now be in place until after school half-term holidays.
After consulting with airlines, a daily limit of 100,000 departing passengers will now apply until October 29, the airport said.
It said the measure would enable more reliable passenger journeys.
When the cap was first announced in July it was initially in place until September 11.
Earlier this month, British Airways suspended ticket sales for short-haul flights from Heathrow as a result of the cap.
The airport said the cap would be kept under regular review and could be lifted early if staffing levels improved.
Primary concern
Heathrow chief commercial officer Ross Baker told the BBC: "Our primary concern is ensuring we give our passengers a reliable service when they travel."
"We want to remove the cap as soon as possible, but we can only do so when we are confident that everyone operating at the airport has the resources to deliver the service our passengers deserve," he added.
In response, a spokesman for Virgin Atlantic said: "We are disappointed that Heathrow Airport has already decided to extend the passenger capacity cap until the end of October, as additional resources come on line every week and the airport experience improves."
The airline said that its ground handler, Cobalt Ground Solutions, which is responsible for services including ramp and baggage operations, currently has staff resourcing at 95% of 2019 levels.
"Airline customers have a right to expect their bookings will be honoured and we're doing everything in our power to minimise disruption, getting our customers to where they need to be smoothly," he added.
Consumer rights group Which? also warned the move will leave thousands of passengers' plans in limbo, saying the situation was a "mess".
Tens of thousands of UK passengers have been affected by travel disruption throughout the summer.
During the pandemic, the aviation industry cut thousands of jobs as international travel ground to a halt. But since then it has struggled to recruit and train new staff quickly enough.
Aberdeen flights suspended
Flights at Aberdeen International Airport were suspended for a time yesterday to allow repair work to be carried out on the runway.
Airport operator AGS said it was to enable the "unscheduled maintenance" to be carried out safely.
AGS said in a later statement on Monday afternoon the work had been completed and full operations had resumed.
