Chase will open the Chase Sapphire Boston Lounge on May 16. As part of this they have announced some unique access rules for the lounge, previously it was through anybody with Priority Pass would be able to access these lounges. The access rules are as follows:
Chase Sapphire Reserve and JPMorgan Reserve cardholders and two guests can access Sapphire lounges for free an unlimited number of times. Additional guests are charged at $27 per guest (children under 2 are free). Authorized cardholders ($75) also get access for them and two guests.
Chase Ritz-Carlton cardholders can bring an unlimited number of guests and visit the Sapphire lounges an unlimited number of times.
Other Priority Pass holders can access Sapphire Lounges once per calendar year for free. This is across the lounge network, not once per individual lounge.
Chase Sapphire & Sapphire Preferred cardholders get no access to these lounges.
When these lounges were originally announced I was wondering what the point was as it was assumed all Priority Pass members would get access to these lounges as they are co-owned by The Club (who run Priority Pass). With only being able to access them once per calendar year it makes a lot more sense. It seems a little weird that Ritz-Carlton cardholders can bring unlimited guests, that could lead to overcrowding just from one cardholder.
