The Foreign and Commonwealth Office has advised against all but essential travel to Israel which comes after Hamas launched a deadly attack on country.
Thousands of rockets are being fired by Hamas fighters and the Palestinian Islamic Jihad (PIJ) to various cities across Israel.
As a result many airlines are pulling out of flying to and from Tel Aviv and Ben Gurion airports.
Wizz Air and Virgin Atlantic have cancelled flight to and from Tel Aviv and British Airways has made changes to their schedule for safety reasons.

On Sunday US carrier Delta Airlines, United Airlines and American Airlines had either suspended or diverted their flights as fighting grips Israel.
In a statement, United said its flights would remain suspended “until conditions allow them to resume”.
Delta said flights “have been cancelled into this week.”
A spokesperson from the Association of British Travel Agents (ABTA) said: “The Foreign Office advises against all but essential travel to Israel and if you are due to travel imminently you should discuss your options with your travel agent or tour operator.
“If you’re travelling on a package and your holiday has been cancelled due to the advice change, you can either defer your date of travel, travel to an alternative destination or receive a full refund.
“If you’re travelling independently you will need to discuss your options with your airline and accommodation providers.”
A Wizz Air spokesperson said: “Due to the situation in Israel, we have cancelled flights to and from Tel Aviv until further notice.
“We are continuing to monitor the situation closely and are in touch with the relevant authorities.
“The safety and security of our passengers and crew is our number one priority and all affected passengers will be contacted via email or text.”
