As a result, holidaymakers will now get twice as many lira for their pounds as this time last year.
The currency shift is expecting to fuel even greater demand for last-minute holidays to Turkey, which has seen an 84% increase in bookings via Thomas Cook alone this year.
The lira, which is the worst performing currency of 2018, fell a further 9.8% against the dollar, on Monday before recovering to end the day 6.5% down.
The pound is now 89% up on the lira compared to last August and 37% up on last month.
