Hi guys, looked at a thread from 2011 about the topic but wanted to confirm if this still holds true:

Im booking a Y award from LHR to CPH and wanted to that me being a GCH would still allow me to use all benefits (First checkin, lounge, seat selections?)

My gut feeling is 90% towards this answer, afterall an economy award should be equivalent on the same merits as a Y full fare booking if I am correct?

Thanks for all info and sorry in advance if this was a dumb question.
