Am a DL Gold/STE+ on a AF-marketed TRN-CDG-LAX itinerary in PE. The booking page shows me as “FlyingBlue Gold.” TRN-CDG is on Hop! and CDG-LAX is on DL metal. I know the TRN-CDG Flight will arrive 2G and DL flights depart 2E-K. The layover is 3 hours 10 minutes.
I would like to visit the refurbished 2E-L lounge. Will I be allowed to do this?
Normally no, but several posters have reported here being able to do it. However, with 3 hrs of connection time and DL boarding ops starting ridiculously early, I would certainly not bother hopping on a different lounge than the one you are normally entitled to. And bad luck for you

, DL is using K and M concourses but never the L one.
