In general . .
Thers a lot of info around the forums but never the less,
STAY AWAY. They will cheat you and go back on all sorts of promises.
Simpley try to get all the great promises in writing, especially begining and ending periods of the program AND what happens if they dont come up with the product.
Promise youll start seing slowly the real face behind it.
Remember, they are not an Airline, Go directly to the companies, youll save money for your self and for the airline.
Simpley make them a better offer then H. does.
Take some time into finding out who they work with and good luck.
Thats the way it shold be. They are not giving you NOTHING for your money that you cant get for your self. Nothing but a middleman.
Best of luck and done fall that way, it will take longer but it will be yours.
Happy new year!!
