Ryanair has confirmed a number of flight cancellations and has predicted significant delays and further cancellations for the rest of the day.
The list of cancellations, posted on its website, comes amid warnings to passengers that European flights in the next two days are likely to encounter delays and disruptions as Air Traffic Control staff are planning to strike in Italy and Portugal.
Passengers planning on flying to Europe in the next two days are likely to encounter delays and disruption to European flights as Air Traffic Control staff are planning to strike in Italy and Portugal.
Airlines are advising customers, particularly those on short-haul flights, to check their websites for the status of their flights, see below for details on where to check the status of your flight.
easyjet will advise all affected passengers on flights into and out of Lisbon and on flights to and from Milan Malpensa via email. Customers can also check their flights on the airline's Flight Tracker page.
British Airways have also re-timed a number of flights to avoid the strike period and have made some cancellations. The airline advised passengers to check its website for up-to-date information concerning flights departing in the next two days.
Ryanair has a list of cancelled flights on their website and has predicted significant delays and further cancellations on Wednesday 29 January. Customers can also check the website for information on how to apply for a refund and how to rebook your cancelled flight.
The European Air Traffic Control services strikes expected over the next two days in Portugal and Italy will have a significant impact on flights, according to easyJet.
The airline said it had pro-actively re-timed some flights later into and out of Lisbon in order to avoid the strike period as well as re-timing some flights to and from Milan Malpensa.
"Like all airlines flying to/ from/and over these countries, we expect it will have a significant impact on our flights during these periods.easyJet would like to reassure passengers that it will do everything possible to minimise any inconvenience for passengers," easyJet said in a statement.
British Airways (BA) have also retimed and cancelled a number of flights to and from Italy, a spokeswoman said.
"We are doing all we can to minimise disruption to customers affected by air traffic control strikes across Europe. We are advising customers on short-haul services to keep checking the very latest information on our website," said a spokesman for BA.
easyJet said the industrial action is likely to continue into Thursday with the French Air Traffic control staff taking part.
EasyJet says its customer service line will stay open until midnight, after many passengers have been left stranded at Gatwick Airport. A power outage at North Terminal has led to cancellations and delays.
A plane has flown through the first-ever artificial ash cloud created in a bid to see how a passenger aircraft can cope with volcanic eruptions.
The experiment by easyJet, who plan to have volcanic sensor detection equipment fitted on its planes, saw one Airbus disperse a tonne of Icelandic ash into the atmosphere at between 9,000ft and 11,000ft.
This created conditions similar to the 2010 eruption of Icelandic volcano Eyjafjallajokull - an event that caused widespread travel chaos across Europe.
A second test aircraft with volcanic sensors fitted to it then flew towards the cloud, identifying and measuring it from around 40 miles away.
A third small plane flew through the artificial ash cloud to take measurements and see how they compared with the data gained by the volcanic sensor detection equipment.
The technology detected the cloud and measured its density which showed that it was within the range of concentrations measured during the ash crisis in April and May 2010.
