Forgive me if this was addressed ( please point me in the right direction): if I have my three FF+ and son qualify for DAS what is the best way to work them? I understand the rules & procedures... But not a logical way to use them together! Before getting in the FF+ line do I run ahead to our next ride ( not FF+) and ask for a return time? And flip flop? I think I read somewhere that at GS that they can give you your first one for the day? Can you use them regardless of the tiers? Thank you for any input... I just made all of my FP+ , my charts and lists have taken over my kitchen table!
