For European operators, long haul destinations may seem to pose the biggest security questions but the safety measures at more frequently visited airports nearer home should be assessed and understood.

According to Avinode, which lists most popular routes for charter brokers and operators wishing to analyse past patterns and future potential, these destinations recently included the UK's Luton and Farnborough, Geneva, France's Aix Les Bains and Cote d'Azur and Germany's Frankfurt.

However unlikely such airports are to feature on ASI's hotspots briefing the advice of professionals is that it is worth checking whether there are any scheduled events that might affect arrivals or departures.

Destinations that ASI recommends keeping under review include Thailand, Jamaica, Trinidad and Tobago, Pakistan, Australia, the UK, Afghanistan, Morocco and North and South Korea.

• There are continued tensions in Kingston since the government began procedures to extradite a supporter of the ruling Jamaica Labour Party to the US. Gangs in west Kingston slums have amassed arms and weapons.
• Post-election disappointment in Trinidad And Tobago may also trigger discontent or travel disruption. ASI says: "Travellers should avoid wearing either red or orange, which are the official colours of political parties and might be interpreted as a form of political activism."
• Afghanistan is always problematic and there is wariness about Mangalore until the reason for an aircraft crash is established.
• North Korea and South Korea have been at each other's throats since the sinking of a South Korean naval vessel that killed 46 sailors on 26 March, South Korea has taken the matter to the UN Security Council and ASI advises that the situation should be closely monitored in case of further developments.
• Bomb attacks in Pakistan have caused concern with events in Lahore's Shahi Mohalla. ASI comment: "The risk of further attacks in major Pakistani cities remains very high."
• It also recommends that a wary eye is kept on Thailand because concerns about new incidents of violence remain.
• Australia has announced that new regulations will be implemented at the country's airports requiring all travellers to declare any pornographic material they are carrying.
• Industrial action is a concern in the UK where discontent continues to simmer after strikes by British Airways cabin crews.
• Morocco is removing foreigners from the country for alleged Christian evangelising activity. ASI says: "Diplomatic tensions with the US have increased recently following Morocco's refusal to abide by the 1998 International Religious Freedom Act."
• Yemen is a source of concern after two US tourists were kidnapped near Sanaa.
• Ethiopia has continued risks of post-election violence.
• Nigeria has suffered religious unrest.
• Togo has suffered kidnapping and ASI says there are heightened political tensions and ongoing economic problems.
• Mexico requires caution with travellers advised to avoid Mexican Federal Highway 15 between Hermosillo and Nogales.

ASI says that security issues rarely affect individuals or organisations in some destinations but others have low-level security issues. These locations have an extremely low rate of violent crime, suffer from sporadic crime, or even regular or rampant crime. "It always pays to analyse and check the risks whatever the destination," it adds.
