As an update to this thread:
President's Club responded to the question of DL FA issuing a Gate Pass for CRC access:
"Thank you for contacting the Presidents Club Service Center.
The Delta Crown room representatives will not give you a pass to go through Security to go to the lounges because their clubs must be available in the terminal that you are traveling out of.
Regards,
xxxxxxxx xxxxxxx
Presidents Club Service Center"
I already have a refundable WN ticket on 3/30 to get behind security. But I intend to ask for a gate pass when I check luggage at MCO and see what happens. I'll update this thread for others in a similar situations.
Too bad we have to go to these lengths to get our reciprical CRC room access. Looks like this maybe more the norm in the future as other rooms are closed and/or realigned.
