Budget airline Ryanair is extending its operation at Liverpool's John Lennon Airport with 11 new destinations.
Ryanair said it was now the biggest carrier at Liverpool Airport
Routes to Santiago, Inverness, Wroclaw, Aberdeen, Kaunas and Ancona officially launched from the airport on Tuesday.
A further five routes - Poznan, Krakow, Tampere, Alghero and Santander - are being launched later in the week.
Ryanair said the huge expansion would make it the largest carrier at the airport in Speke. The budget airline will now run 34 low-cost routes.
UK Sales Manager Caroline Baldwin said traffic had increased eight-fold since Ryanair launched its first service from Liverpool in May 1988.
"This week we are delighted to add 11 routes from the north-west which will deliver 600 new jobs, 600,000 more passengers and £80M additional tourism spend in Merseyside," she said.
The new services include daily flights to Aberdeen and Inverness and four flights a week to Tampere in Finland.
