There's gotta be some disconnect here.

Either the systems you're looking at are not reflecting accurate info for the aircraft type (meaning COPA's MAX9s are actually sitting on the ground and a different aircraft type has been swapped in), or COPA is asking for a serious smackdown from the FAA (or potentially worse). Imagine how things would go for any airline if a 737 MAX9 they're now flying (in clear violation of the emergency AD now in effect) had an explosive decompression event after they ignored the clear, well-publicized mandates from the FAA to ground the planes...

As someone who is scheduled to fly on a COPA MAX9 in about 6 weeks and again in the future, I hope (and would assume) COPA is following the mandates and playing by the rules. If they're not, I'll have second thoughts about ever setting foot on one ANY of their planes.

Edited to add: If COPA's website is to be believed, their 737MAX9s are grounded, and will remain so, until the FAA and Boeing get things sorted out with the required inspection details, and then they perform the required inspections. The ball seems to be in Boeing and the FAA's court right now (and has not moved in 24 hours...). Hmm.
