Justfly sold me a flight to Europe that they listed as "Economy". After purchase, they sent me a copy of the itinerary (on a JustFly proprietary form) listing the flight as "Economy". Lo and behold, when I check the flight confirmation number on Lufthansa, it's listed as "Economy Light". On Lufthansa, "Economy" gets a checked bag, and "Economy Light" gets zero checked bags.
This is a cut-and-dried bait and switch. Eminently dishonest. And I got these tickets for all of my family.
Justfly may well respond with some gobbeldygook, but that would be dishonest too. Because, you see, Justfly gives you a link to check the baggage policies of the carrier you book with... and guess what? Lufthansa gives you a free checked bag with "Economy". So if I got the ticket promised by Justfly, I'd have a free checked bag.
Justfly is intentionally dishonest.
Be warned.
