I'll take a crack at this, although I agree with chrylis that it's a little hard to figure out for sure what you are asking.

"Always the same, isn't it? 'Poor old Cuthbert, doesn't listen to a word you say...head in the clouds again...always gets the wrong end of the stick.' And on and on and on and on and on!" ranted Cuthbert.

Okay, forget about the airport and the context of the story. You have a group of people together, and one of them feels like the others think he's foolish. So he starts a rant:

Always the same, isn't it?

That means: No matter what we're doing, you think the same thing of me.

'Poor old Cuthbert, doesn't listen to a word you say...

Cuthbert is talking here, so he is saying what he thinks everyone else is thinking about him: namely, that he doesn't listen.

...head in the clouds again...always gets the wrong end of the stick.'

means: Cuthbert doesn't pay attention to what's going on around him; Cuthbert always finds himself confused in life.

And on and on and on and on and on!" ranted Cuthbert.

Means that he could keep going with his grumbling rant, if he wanted to, adding things like: Cuthbert always has his head up his ass, Cuthbert never does anything right, Cuthbert couldn't find his way home if you gave him a map and paid for his taxi fare, etc.

Because the "d" in "Dodge" should have been capitalized. But the "Dodge" being referenced was not a make of car, but rather a place, namely "Dodge City," which was for a few years one of the wildest towns in the "Wild West." It was for a number of years the terminus of the cattle drives from Texas, where the herds met the railroad.

Because Dodge City was a very violent place for a number of years, it was frequently prudent to leave it behind expeditiously.
