I'd move it to the noon flight. I don't know how the specific disembarking procedure will be but it would still be too tight, especially id it could take 2 hours to start disembarking. The drive from the cruise port to the airport takes 30-40 minutes. You can take a taxi or a shuttle if there is one or just get an uber, its around $30 for an uber from the port to the airport.

For context, Red is the cruise port and cruise port building, in light green is the current dirt road and the yellow X is where I took the picture from, the main road and port entrance. You can also see Perico island and the plaza there and all the way on the bottom you can see Flamenco Island and its plaza.

I drove past the terminal entrance yesterday and took this picture. As you can see its still a dirt road with not much infrastructure. Also drove past flamenco island and there is not much to show about cruise ship check in, not saying its not there but that currently I didnt see any stands or anything.

I would not be able to confirm about any of the specifics about getting on and off the cruise since i haven't boarded a cruise from Panama. Regard taxis/cabs, they will be avaiable at all touristy spots you may go to, Casco Viejo, the Causway, Miraflores, the airport etc. They are also available along the street wherever you want and see one. However some may want to charge you extra for being tourists. Overall they are a valid option but I'd keep Uber open as an option as they are pretty cheap here compared to in the US and the prices are confirmed by you, not them.

As bill said is correct, here you can see each tide cycle for the next month:

Yes the cinta costeras are beautiful and a joy to take a drive on, the views they give of both the city and ocean are stunning.

Hello everyone, I just came across this forum and saw it interesting. I am currently living in Panama City so I've driven past the port many times. Ships dock there however the main port building is not finished, people are still boarding via busses and ramps. I am not sure about any specific cruise line check in procedures as I have not boarded a ship from here but I am pretty knowledgable about the rest.
