For getting 100k benefits to other members on the itenary, try the following.. start without logging in, select regular fare (discount dden doesn’t work as it forces you log in), on the screen to enter passanger info, log in, it populates the first passanger info but will have an option to uncheck first passanger info to clear. Renter your frontier #, info (remembers bday!) and then other passanger info without frontier numbers. It will let you go to next screen with bundle package applied. I booked a trip with 4 of us yesterday with those steps.. good luck..
