Fledgling operator FlyLolo has confirmed an expanded range of destinations to be served for this summer.
The company run by former Avro boss Paul Dendle ran an initial programme from Southampton airport to Skiatos between July and October 2018.
The company has also been running winter sun flights from Gatwick and Manchester to Tenerife.
Seven new destinations in Greece, Spain, Croatia, Bulgaria and Montenegro are now being offered this year from the south coast airport for summer 2019.
The firm, specialising in peak season flights, was the first to fly to Greece from Southampton airport and has issued an extended programme for 2019.
Tui is also running flights from Southampton to Malaga, Majorca and Ibiza this summer.
Other destinations being served from the airport include Verona, Faro, Corsica, Alicante, Malaga, Toulon and Avignon.
Airport managing director Neil Garwood said: “I am very pleased with our summer campaign this year.
“We are working closely with our business partners to offer more choice, and we are really looking forward to seeing passengers jetting off to sunny locations to enjoy their summer holidays.”
