Let’s start with the shoes. Firstly make sure they slip off easily, you are going to have to take them off at least 3 times at every airport. You are also going to want them to be a little loose to accommodate your swelling feet.  Make sure they are sturdy and non slip. You going to need all the traction you can get running down airport passages to get to the furthest gate.

Now to the pants. The only advise I can give is Cargo’s, Cargo’s , Cargo’s. They nice and comfy, a bit baggy and most of all have loads of pockets to stash you passport, tickets, lip ice, chewing gum and anything else you need on you all the time. Do make sure that they are not elasticized, otherwise the weight of the stuff in your pockets may drag them down. Wear a stout belt for partner to yank on to get you out of the way of luggage carts.

For tops, dress in layers to accommodate the climate changes you will encounter. Also wear colors that hide all the times you slosh your drink during turbulence.

Top that all off with a hat to hide “plane hair” and you should be pretty comfortable.
