As the security situation worsens, major airlines around the globe have canceled flights to Israel or warned of travel disruptions.

British Airways (BA) has altered its schedule and Virgin Atlantic has issued a travel advisory for Tel Aviv.

Three US airlines, along with Air France, Lufthansa, and Emirates, have suspended operations. Monday, Palestinian militant group Hamas reportedly fired missiles at Israel's Ben Gurion airport.

Since Hamas launched its assault on Saturday, approximately 700 Israelis and 500 Gazans have died in retaliatory airstrikes.

The Foreign Office advises against all but essential travel to Israel and the Occupied Palestinian Territories, as well as travel to certain other regions in the region.

Virgin Atlantic has canceled eight flights between Tel Aviv and London Heathrow between Saturday and next Wednesday. "The safety and security of our customers and our people always comes first and our flying programme to Israel remains under constant review," according to a spokesperson.

Wizz Air, a low-cost airline based in the United Kingdom, confirmed it had canceled all flights to and from Tel Aviv until further notice, while EasyJet suspended flights on Sunday and Monday and altered its schedule for the remainder of the week.

British Airways has moved the departure time of its daily flights from Heathrow to Tel Aviv to the morning, moving them from the afternoon slot.

It is common knowledge that the reason for this is to spare the crew the necessity of spending the night in Israel.

The airline issued a statement saying that it was monitoring the situation closely.

According to a spokeswoman for the company, a flexible booking policy had just been implemented so that customers may change the dates of their trips at no additional cost if they so desired.

On Monday morning, the flight tracking website FlightRadar24 displayed that there were still some planes arriving in and departing from Tel Aviv.

Among these were aircraft operated by Ryanair and Pegasus. However, Ryanair later said that it was forced to cancel a number of flights to and from Tel Aviv on Monday and recommended passengers to check for the most recent flight updates.

The cancellations were due to weather conditions. On Sunday, United Airlines, Delta Air Lines, and American Airlines all announced that they would be suspending direct flights to Israel effective immediately.

Delta has informed customers that their flights "into this week" have been canceled.

Meanwhile, 300 citizens of Poland and Hungary have been airlifted out of the country, and it has been reported that Thailand and Nepal are contemplating doing the same thing.

According to a representative for the Association of British Travel Agents, holidaymakers who are planning to travel to Israel in the near future should explore their choices with their travel agent or tour operator as soon as possible.

They mentioned that if someone is taking a vacation through a tour company and the trip has been canceled because of a change in the government's recommendation, they have the option of either postponing their departure date, traveling to a different location, or receiving a full refund.
