Between 2022 and 2027, the Lufthansa Group will receive a total of 32 Boeing 787-900 "Dreamliners". The first were delivered in late August 2022 and tested on flights between Frankfurt a.M. and Munich Airport. The first Dreamliner was christened on October 17th 2022 and the inaugural flight took place from Berlin via Paderborn to Frankfurt. Later, the first public test flight was LH 96 on October, 19th 2022 from Frankfurt to Munich as shown on the cover below. The cancellation on the stamp shows "Frankfurt - Flughafen - IPZ 1" (Frankfurt Airport), after a flight of about an hour the cover arrived at Munich Airport which can be seen on the added "Briefzentrum 85" cancel. The red special postmark was applied to indicate this testflight.

I'm also happy about this cover below showing the flight the other way back from Munich to Frankfurt Airport.
