More than 250 new jobs will be created with Jet2.com and Jet2holidays starting a network of low-cost leisure services from Stansted next summer.
Vacancies cover flight and cabin crew, engineers and ground operations staff.
The airline has put 21 destinations on sale and will be the only carrier to fly to Madeira from the Essex airport – a major hub for Ryanair – with two flights a week.
Jet2holidays is expanding its trade team with the appointment of a sales executive who will be dedicated to Stansted to support agents in the region. Trade booking account for a third of all business for the operator.
The network from the group’s ninth UK base covers Lanzarote, Malaga, Alicante, Dubrovnik, Faro, Madeira, Fuerteventura, Girona, Crete (Heraklion), Ibiza, Kos, Larnaca, Gran Canaria, Menorca, Paphos, Majorca, Pula, Reus, Rhodes, Tenerife and Zante with as many as 83 flights a week scheduled.
The airline is to base six new Boeing 737-800s at Stansted giving a capacity of 800,000 seats from spring 2017.
An initial 50,000 seats have been released at £30 one-way to mark the introduction of the new flights.
The first services from Stansted are due to take off on March 30, 2017, to Alicante, Faro, Majorca and Lanzarote.
