I'm a little disappointed with myself that I never got a Cabin Pressure icon and the series is now over!

I pretty much agree with everything you've already said. I'm pleased that Arthur got to be smart (twice!) for Arthur at least for the ID thing and for remembering his Gran's real name. The show also did my favorite thing of having characters imitate each other with Martin being Douglas and Douglas being Gordon and Arthur being...his Aussie alter ego. Top points for everyone's imitations!

I think my favorite moment though was when Carolyn announced that Douglas will be captain. Like the audience, I actually paused to take that in before I got all teary eyed and aw'd. I'm so pleased that everyone got something at the end.

Martin's captain at Swiss Air is Captain Loutre, which is 'otter' in French.

I didn't know this! That's such a great detail. It was sweet that Martin clearly has retained the humor he was more or less forced to develop during his time at MJN Air. "Martin du Crieff..." It would have only been better had he somehow worked in bear polar.

I also hope there will be maybe a future Christmas special at some point. I'd like to know how Martin's getting on at Swiss Air and how OJS is doing.
