This German airline will book you a cheap flight - but the destination is a surprise

Airlines have been under increased public scrutiny in recent months, following an incident in which a United passenger was violently removed from an overbooked flight.

But a top German carrier wants to give fliers something to smile about.

Lufthansa, the largest airline in Germany, is offering an option that lets people book a flight to a surprise destination. Called the "Lufthansa Surprise," the deal allows passengers to choose from nine categories - including nature, shopping, and "bromance" - and pick their travel dates.

The airline will only reveal where the passenger is going after they complete their purchase.

Passengers might end up in popular European tourist destinations like Rome, Madrid, and Paris - or have the chance to explore less trafficked cities like Warsaw, Poland; Turin, Italy; or Izmir, Turkey. Customers can opt out of cities, though being selective drives up the cost.

Lufthansa started offering blind bookings in spring 2016. The round-trip flights start at €89 ($99), which is cheaper than the average fare.

"The more flexible you are, the cheaper your flight," the Lufthansa website says.

Unfortunately, the flights only depart from Munich and Frankfurt airports, so people from other areas would have to spend hundreds more to get Germany if they want a Lufthansa Surprise.

Once a ticket has been purchased through Lufthansa Surprise, no refunds will be given - so if you're prone to buyer's remorse, this deal might not be for you.
