hello FT'ers:

i bought my cousin a graduation gift that includes club world DEN-LHR-ATH (club europe i know).

so my question is this: when she checks in at DEN, will her bags be checked thru to ATH or just to LHR?

mind you she arrives LHR at 1200 or 1300 the next day...and leaves for ATH the FOLLOWING day.

she has never transited LHR and i am trying to write her detailed advice but clearly the baggage retrieval is part of that--if relevant.

thank you!

PS: if the bags cannot be checked thru, what is the max allowable layover where your bags would be checked thru?
