Tour operators and cruiselines have extended their suspension of holidays to Mexico as the Foreign Office continued to warn against all but essential travel to the country.
Thomas Cook has cancelled its Cancun programme up until May 14, while TUI has cancelled flights to Cancun and Cozumel up until May 12. Customers can postpone their trip or change their destination.
Some airlines are still flying to Mexico but have cut capacity due to lack of demand. Continental Airlines has reduced its overall capacity by 50%, while US Airways is cutting back on departures to Mexico in May and June by 38%.
British Airways is continuing to operate flights from Heathrow to Mexico City.
Cruiselines are also taking action. Carnival Cruise Lines has cancelled all port of call visits in Mexico for 16 of its ships.
Itineraries for Carnival ships departing between now and June 15 have been modified, in most cases substituting Mexico for an alternative port.
