Both Jet2 and Tui confirmed trips due to depart up to, and on, Wednesday (4 November) would operate, despite prime minister Boris Johnson on Saturday (31 October) announcing a new month-long national lockdown until at least 2 December, which effectively bans non-essential travel.
EasyJet Holidays, though, has confirmed all holidays due to depart up to 2 December would be cancelled.
Jet2holidays said that while it was working with government to obtain "much-needed clarity" about what the fresh lockdown announcement meant for those planning to holiday overseas, it was "planning to operate as normal between now and Wednesday (4 November).
"Customers wanting to get away from the cold and gloom can still book and travel as normal," said the operator.
"For customers due to depart up to and including Wednesday 4 November, and who do not wish to travel, they can amend their booking to a later date with no admin fee.
"If flights or holidays are affected by any changes, we will contact customers to advise them of their options. Customers in resort should continue to enjoy their holidays as planned."
Tui, meanwhile, said all holidays due to depart between Sunday 1 November and Wednesday 4 November were currently due to operate as planned, adding customers due to travel before Thursday could amend their holiday to a later date for free.
"We understand holidays abroad (for those living in England) are unable to take place from 12.01am on Thursday 5 November," said Tui. "As soon as we have more information, we will be updating customers as soon as we can.
"If holidays are unable to take place, customers will be notified and offered the option to amend with an incentive, receive an Atol-protected refund credit note with a rebooking incentive, or cancel and receive a full cash refund within 14 days.
"Customers currently on holiday can continue to enjoy their holiday as planned."
EasyJet Holidays said it was proactively contacting all customers affected by the government’s new lockdown announcement, which it said effectively "bans all leisure travel" and "sadly means holidays up to 2 December cannot go ahead as planned".
Customers will be able to change the date of their trip for no fee, take easyJet Holidays credit to use against a future holiday, or opt for a full refund.
"While outside of our control, we’re really sorry so many customers are having their holiday plans disrupted and thank customers for their ongoing patience and understanding."
The operator added with there being uncertainty around bookings beyond 2 December, its trips were covered by its protection promise – and that it would work through future bookings in departure order if the lockdown is extended.
