The situation in Turkey appears to be calming following the attempted coup on Friday night, according to the Foreign and Commonwealth Office.
Security operations to detain alleged perpetrators continue across the country with reports of gunfire.
“We are aware of such action in Konya, Marmaris, Van and at Sabiha Gokcen airport in Istanbul, which remains open and operating as normal,” the FCO said in it latest travel advisory issued last night.
British travellers were warned to continue to exercise caution as the security situation “remains potentially volatile”.
“Apart from Marmaris, the coastal resorts do not appear to be significantly affected at present,” the FCO added.
“You should check with your airline or tour operator before travelling to the airport. Continue to exercise vigilance in resort areas.”
As many as 6,000 people are reported to have been arrested following the failed coup while almost 300 were killed in weekend violence which saw tanks on the streets of Istanbul.
US aircraft were banned on Saturday from flying to Turkey by the Federal Aviation Administration which said it was monitoring the situation in the country and will “update on restrictions as the situation evolves”.
Meanwhile, the FCO said: “Following earlier disruption, flights to and from airports in Turkey are returning to normal, although some disruption remains and you should check with your airline or tour operator before travelling.
“You may need to turn up at the airport earlier than normal to get through the additional security checks in place.
If you are in Turkey, please follow the advice of the authorities, closely monitor travel advice and contact your airline or tour operator.
“In Ankara and Istanbul we advise you to avoid public places, in particular demonstrations, and remain vigilant.
“Take sensible precautions if you are in the vicinity of any military or security forces. Roadblocks are in place in some areas.”
Regular operations resumed at Istanbul’s Ataturk airport on Saturday.
British Airways said: “Our flights to Turkey have resumed but we continue to keep our flights to the country under review and will update this content with the latest information.
“The safety and security of our customers and crew are always our top priority and we would never operate a flight unless it was safe to do so.
Thomson said all flights to Dalaman, Antalya, Izmir and Bodrum would be operating as normal, including those due to depart today (Monday).
“The safety and security of our customers and crew is our highest priority and like all airlines and holiday companies follow the advice of the UK government and the FCO,” the operator said.
Thomas Cook said: “Our flight and holiday programme is operating as normal and our staff on the ground in resort tell us is that everything is calm and customers are enjoying their holidays.”
However, the operator offered free amendments and cancellations for all customers due to fly to Turkey on Sunday.

Turkish Airlines said passengers due to travel up until Wednesday could re-book flights free of charge.
Abta estimates there are currently 50,000 people on holiday in Turkey with member companies.
“The vast majority of British travellers to Turkey will fly directly to the beach resorts on Turkey’s south coast which are hundreds of miles away from Istanbul and the capital Ankara,” Abta said.
“The FCO is reporting that the coastal resorts do not appear to be significantly affected at present and advises holidaymakers should check with their airline or tour operator before travelling to the airport and continue to exercise vigilance in resort areas.
“People in Ankara and Istanbul are advised to avoid public places, in particular demonstrations, and remain vigilant.”
