The international airport in Kerki is trying to attract foreign airlines with free aircraft service, according to the official website of the Turkmenabat airport (Kerki airport does not have its own website).
“At Kerki International Airport, free ground services are provided, with the exception of air navigation and fuel charges, for a foreign airline making a technical landing when refueling at least 15 tons of fuel,” the announcement says (verbatim quote with spelling and style preserved).
It should be noted that 200 kilometers from Kerka there is a larger international airport in the city of Turkmenabat with a capacity of 500 passengers per hour, which was opened in 2018. Judging by the reports on the website of the international airport of Turkmenabat, cargo and passenger aircraft of foreign airlines periodically make technical landings there. Thus, the two airports are in direct competition with each other.
The airport in Kerki with a capacity of 100 passengers per hour was opened in June 2021. At the moment, judging by the flight schedule of Turkmen Airlines, flights from Ashgabat, Dashoguz and Turkmenbashi fly to Kerki.
In April, it was reported that Turkmenistan was trying to attract foreign cargo airlines to its airports by promising low fuel prices and free landings and services at Dashoguz and Mary airports. British Coyne Airways received a license to sell Turkmen kerosene. On the company's official website, it was specified that prices would be updated every month, but this does not happen and the site has not been updated since March.
