Hi all, sorry for a newbie question. I will be flying through Frankfurt on Lufthansa a few times in the very near future. I currently have a Priority Pass card through my Sapphire Card and have been on the fence for a while about upgrading my Amex gold to platinum. Are the Priority Pass access lounges in FRA very nice or is it worth upgrading to the Amex Platinum to get access to the lounges that it provides? Also, do any of the lounges I can access have kosher food? Thanks in advance for the help!
