The National Air Traffic Service (NATS) has warned British airspace is likely to be closed until lunchtime tomorrow at the earliest, with severe disruption expected into next week.
But what alternatives to air transport are there? Here Breaking Travel News takes a look.
For those looking to cross the English Channel, SeaFrance confirmed earlier this morning a foot passenger service would be added on selected sailings today.
In response to demand the ferry service has added foot passenger availability to sailings at 11.25, 12.30, 15:50, 16:50 and 20:00.
Foot passenger services will also be available on Saturday morning. Space is also available for car passengers on all crossings.
Head over to SeaFrance for more information.
P&O Irish Sea services are also currently operating to schedule, with spaces available for both vehicles and foot passengers on the Troon and Cairnryan routes.
Tickets can be purchased at the port but passengers are advised to allow a little extra time.
With 50 crossings over the next three days between UK and France, as well as UK and Spain, Brittany Ferries can also offer an alternative to holidaymakers.
The operator offers departures from Portsmouth and Plymouth to Caen, St Malo, Cherbourg, Roscoff, and Santander.
European coach operator Eurolines has announced the addition of further services to key destinations across Europe, with the situation under constant consideration.
The operator provides regular services across Europe, with high frequency services from London Victoria to Dublin, Paris, Brussels, Amsterdam and Cologne.
Channel Tunnel and sea crossings, travel taxes, road tolls and luggage are all included in the price with no expensive transfers.
To check availability and book online head over to Eurolines.
There are also a very limited number of seats available on Eurostar services.
A statement on the train operators website read: “Due to the disruption to air travel in Europe, Eurostar trains are extremely busy.
“We would ask that you only come to our stations if you hold a confirmed reservation for travel.”
