A Viking Hellas aircraft was impounded at Gatwick airport on Monday for non-payment of fees.
The aircraft was later released after Viking Group settled the payment.
In a statement, Gatwick Airport said: “We can confirm that a Viking aircraft was detained by Gatwick Airport yesterday (18 October) as a result of an unpaid, long-standing debt owed by Viking Group.
“Gatwick did not take this action lightly, but after months of chasing payment without success it became apparent that this was, regrettably, the only option left to recover the monies owed. The aircraft was released following the receipt of payment made by Viking Group.”
Greek airline Viking Hellas is expected to run services for its sister carrier Viking Airlines AB over the winter period.
Viking AB has had its operating licence revoked until March 31 2011. A statement on the Swedish regulators’ website said the airline “can no longer fulfill its obligations under the EC Regulation governing the conditions of operating licenses for EU airlines”.
A spokesman for the airline said it would restart operations for next summer.
