Didn't realize they are part of the lastminute.com scam till quite late unfortunately. Scumbags list the tickets a few dollars less than the rest everywhere they can and keep shifting buttons and options on the booking screens to trick you to pay for more useless add-ons. Steer clear or be very careful before clicking anything. They stole $75 from me.
Completely unhelpful customer support and refund took 1+ month to arrive after sending notices via the credit card company. Then had to further hassle them to return money instead of "airline credit "!
They are not based in USA, so good luck enforcing US laws like full refund for bookings cancelled under 24 hrs!
