Monarch is adding three additional flights from Gatwick to Faro in the peak summer weeks, taking the number of weekly services to 12.
The extra flights will depart on a Monday, Wednesday and Friday and operate between July 31 and September 1.
Managing director Tim Jeans said the expansion follows an increase in Faro bookings of 60%, fuelled by the introduction of daily flights from Birmingham and increased frequency from Manchester and Luton.
The carrier also announced an increase in flights between Manchester and Palma over Easter.
