Wizz Air is to add new routes from Bristol and Aberdeen to the Polish capital Warsaw in 2016.
The Hungary-based carrier has decided to base a sixth aircraft at Warsaw from May next year which will be used to serve the two new UK routes, plus services to Bari in Italy and the Icelandic capital Reykjavik.
Both new UK routes will operate from May 13 with the Aberdeen flights operating on Monday and Thursday, and the Bristol service running on Wednesday and Sunday.
Wizz is also to start a twice-weekly route between Birmingham and Poznan from December 18, which will operate on Monday and Friday.
As part of its expansion from Poland, Wizz will add extra frequencies from Warsaw to existing UK routes from May 13, 2016.
Warsaw-Luton flights will be increased from 23 to 26 per week, while Doncaster flights will rise from three to four per week and the Birmingham service will go up to three weekly services from the current two per week.
