The cost of flights could rocket after the UK's lockdown ends, meaning flying overseas becomes unaffordable for many.
The number of global flights has plummeted 80 per cent since the start of April, according to the Air Transport Association, with more than two million flights now cancelled.
However, the moment travel bans are lifted prices could increase significantly, The Mirror reports.
While the majority of passenger flights are now grounded, demand is building up as people look to reschedule holidays for later in the year.
But when planes are actually allowed to take off again, there could be new social distancing rules still in place meaning carriers are not allowed to fill up all their seats.
An industry expert says this means airlines could be forced to pass on the increased prices to travellers.
"There are currently cheap fares available but this pricing is based on a full plane," the expert told the Telegraph.
"The profit margin on a single seat is around £5 on average, so it is inevitable that ticket prices will have to go up to maintain this, if only a proportion of seats are allowed to be sold."
The expert also said inflated prices could be expected to last months as airlines seek to retain profit.
Given IATA figures show airlines have lost an estimated $314 billion since the coronavirus pandemic began, it could mean cheap flights might not return for months after travel bans are lifted.
Domestic markets could be the first to reopen, according to the trade body that represents airlines such as Lufthansa and British Airways owner IAG, with international routes following afterwards.
The news comes as a consultation for people to have their say on plans to increase summer night flights from Bristol Airport has been extended.
