Today I had a flight with EY (AUH-DOH). I am FB PFL. Had a Y ticket issued by EY.
On my paper boarding card I was nothing special.
In the EY app, the digital boarding card said I was Platinum and that I have lounge access and priority boarding. I found this out just before boarding but thought I’d check if the lounge access worked. The guy at the entrance wanted let me in, and that was when I started asking questions why I have lounge access. Eventually also ended up talking the the manager and she said I should not have lounge access, she also did not even allow me in any more. Which was no issue is my flight was boarding.

But if one is on a EY Ticket and Flight with FB status its worth checking the app and if it shows lounge then don't ask questions.

Priority boarding was no issue with the digital boarding card.

Last month I had a whole lot of abbreviations on my bc from EY, I had won a bid for upgrade so had lounge access. That time the paper bc also mentioned plat.
