Parents have booked with Virgin Atlantic. EDI-MCO (Upper with VA) but return flight is with Delta. MCO-JFK (First Class) then JFK-EDI (Delta One)

I know they will definitely get lounge access at JFK with their Delta One boarding card but my question is will they qualify for lounge access at MCO? I checked the Delta website and the wording is very ambigious...........

"Customers travelling on Delta One on an international Delta flight or on a domestic flight connecting to/from a same day international Delta One Flight"

so does their domestic first class flight MCO-JFK qualify for lounge entry at MCO because they are connecting to a Delta One in JFK? Asked on twitter and the agents were none the wiser and google is not being my friend today. Appreciate your advice.

I don't see a problem here - they are connecting to the same day international Delta One flight, so they do get lounge access at MCO

There is no ambiguity, your parents are "on a domestic flight connecting to/from a same day international Delta One Flight" and will have access at MCO.

Note at JFK they will have access to the Virgin Clubhouse and both SkyClubs.

Thank you - I wasn't sure if the wording meant the domestic flight also had to be Delta One

They would also have lounge access at EDI on the departure.
