The airline and operator will start flying to Spain's Reus from Bournemouth the summer after next. Edinburgh, meanwhile, will gain new routes to Chania in Crete and Croatia's Pula.
All three routes are exclusive to Jet2 at its Bournemouth and Edinburgh bases. It follows the addition of Gatwick-Lesbos – another summer 2027 route exclusive.
Jet2 will also up capacity at Gatwick, its newest base launching next month, by more than a quarter for summer 2027, and is adding 30,000 more seats to its summer 2026 Greece programme.
Sunday Bournemouth-Reus services will operate from 2 May 2027 to 31 October 2027, opening up the Costa Dorada to customers on the south coast, growing Jet2's network at Bournemouth to 18 routes.
At Edinburgh, Jet2 will fly to Chania once a week on Wednesdays (5 May 2027 to 27 October 2027) and once a week to Pula on Sundays (2 May 2027 to 17 October 2027). It means Jet2 will serve 40 destinations from Edinburgh in summer 2027.
Steve Heapy, Jet2.com and Jet2holidays chief executive, said: “There are many holidaymakers wanting to get that sunshine locked into their diaries for summer 2027.
"In response to demand from those customers wanting to book early, who know the best rooms in the best hotels in the best resorts get booked up, we are delighted to be putting three new destinations on sale."
