Bad Air Day
Show canned hints
The boarding passes all reference a certain type of event (which is not related to aviation). It may be useful to think about the set of "From" cities.
This puzzle is about unusual fashion shows (the sole reason for the aviation theme is so we could make the "runway" pun).

Google is helpful for finding some of these shows (e.g. queries like "popcorn fashion show" should bring up the right results, which you can confirm with the location/date). The boarding passes are sorted in alphabetical order by brand, which can help with researching the harder ones.
For each of the fashion shows, the first (or one of the first) look matches one of the planes.
Index the number on the plane into the name of the matching brand. You will get a phrase that indicates some action you need to do - submit this phrase into the answer checker for more information.
