Just slightly OT---

Just got a status upgrade to MPC Silver this week due to company corporate contract.

Two questions:

1) Does MPC Silver access to "Business Class Lounges" include access to contract lounges at JFK/airports that do not have a CX operated lounge?

2) If answer to #1 is yes: I will not receive my MPC card prior to my flight next week. Should I ask for a lounge invite during checkin?

Mahalo!
