Hi
Amy - as you likely know the iPad Air 2 has a standard 3.5 mm port for a headphone jack - any type of 'in the ear' (e.g. ear buds) or 'over the ear' headphones will work w/ that port; of course, you might want to consider a set of 'noise cancellation' headphones being on a noisy plane (cost more) - if you go that route and might have a friend coming along who wants to also watch the movie(s), then consider buying an inexpensive stereo audio splitter like the one shown below.
Of course, your other option if a cabled connection is not desired is to use some BT (Bluetooth) headphones - I have several small ear bud types and also several over the ear headsets (the BT wireless technology is my choice) - good luck in your selection(s). Dave
