Lufthansa Group is to resume 115 weekly services from UK and Ireland from June 15.
Eight new routes have been introduced from Heathrow, Manchester, Birmingham, Edinburgh and Dublin.
Three new routes from Heathrow are to Munich with Lufthansa, to Vienna with Austrian Airlines and to Brussels with Brussels Airlines.
Two new routes from Manchester are to Zurich, with SWISS, and to Brussels, with Brussels Airlines; Manchester will have a new Lufthansa service to Frankfurt; an Edelweiss flight will link Edinburgh to Geneva; and SWISS will fly from Dublin to Geneva.
The German airline group is to offer more than 2,000 weekly connections to more than 130 destinations worldwide across its airlines by the end of next month, including 34 additional destinations from Munich and 20 from Frankfurt. June flights went on sale on Thursday.
Andreas Köster, senior director sales UK, Ireland and Iceland for the Lufthansa Group carriers, said: “By resuming a part of our schedule in June, the Lufthansa Group is building up mobility by connecting the UK and Ireland again to our worldwide network.
“This is an important contribution to support the restart of industry and commerce, but also the tourism sector – both essential for the UK and Irish economy. People want to and can travel again, whether on holiday or for business reasons.”
In addition, 34 long-haul destinations offered by Lufthansa Group airlines have been reintroduced. The airlines now offer 112 weekly connections to destinations outside Europe.
Lufthansa Group warned customers to consider countries’ individual entry and quarantine regulations when planning their trips, adding that restrictions may apply due to stricter hygiene and security regulations during travel, which could lead to longer waiting times at airport security.
Onboard catering services will remain restricted “until further notice” and passengers are required to wear a face mask throughout the entire journey.
