The Copa flight from PTY-SFO was a Max 9 on Saturday, flying back to PTY early on Sunday, but yesterdays PTY-SFO flight was not the Max 9. A note on the Copa website yesterday morning indicated they would have all the Max 9's back up and running within 24 hours. We are set to fly SFO-PTY at 0045 tomorrow morning, so I'm watching the Flightaware website with great interest, as we are flying business class. I'll know what plane we are on in about 4.5 hours, after the flight from PTY-SFO takes off. Fingers crossed!
