Yep, that's what I was told so I am taking a business class fifth freedom flight.

I use Expertflyer but the info is limited, based on seatguru reviews.

Unfortunately they only have an enquiry template on their webpage.  It took me forever to sort out my tier status after qualifying.  They don't even have a phone number.  Suggest you call the recalcitrant airline.

After experiencing F in SQ's A380, I felt so cramped in EK.

I am now much more confident of retaining my Tier in 2024.
