Lufthansa Group airlines appear to be offering some sort of flash sale or error fare between the United States and Europe. Multiple outlets are currently reporting on the sale and are showing different routings and availability, but be advised that inventory and pricing is changing rapidly.
While others have reported fares as low as $1100 from multiple US airports, the cheapest I’ve found is between Philadelphia and Prague for $1118. Jfkeze posted the deal on FlyerTalk and it seems that the key here is to fly Lufthansa Group leisure subsidiary Discover Airlines on the transatlantic legs. Some of the return flights require overnights but at this price that’s worth it.
The range of dates seems to be available on sporadic sporadically from April 2025 to February 2026. I’ve also found options for slightly more money to Amsterdam (AMS) and other airports across Europe.
This deal certainly won’t last long so head on over to Google Flights and, if you see something you like, book it ASAP!
Summary
Lufthansa Group appears to be running a flash sale on flights between the United States and Europe ranging from April 2025 to February 2026. Others have reported this fare available on Lufthansa metal, including its A350s, from Dallas/Ft. Worth, Chicago-O’Hare, and Miami but the lowest fares I’ve seen are on leisure subsidiary Discover Airlines between Philadelphia and Europe.
