A drunken air passenger who was cast away on a remote Atlantic island could be handed a £3,000 bill for the detour.
The man, 53, from Preston, Lancashire, was dumped amid claims he swore at cabin staff when refused wine on the Monarch Airlines flight to Tenerife.
He was marched off by police on Porto Santo, a Portuguese-run island, after the pilot made the unscheduled stop.
Monarch said it was lodging a complaint with Greater Manchester Police and taking action to recover its costs.
The breakdown of costs include landing charges, navigation charges, handling charges and extra fuel.
A company spokeswoman said: "Monarch Airlines is to take action against the passenger to reclaim the additional costs incurred as a result of the diversion."
It is alleged the passenger became aggressive towards cabin crew and fellow passengers onboard Monarch flight ZB558 from Manchester on 27 December.
"Despite repeated attempts by the crew to calm him, his disruptive behaviour continued and the decision to divert the flight was taken," the spokeswoman added.
"Monarch Airlines will shortly refer all of its internal reports regarding the incident to the airport sub-division of Greater Manchester Police, formally requesting that the matter be investigated."
After the incident the plane and its remaining passengers took off again for Tenerife, where it landed almost four hours late after the unscheduled stop.
The Atlantic island, which is 10 miles long and three miles wide, is a two-hour ferry journey to Madeira.
