An interesting discussion arose recently about appropriate airline etiquette. Do you ever consider what you wear on an airplane? Perhaps you don’t because you think paying $12,000 for the business-class seat entitles you to wear whatever you want. But do you think so-and-so across the aisle paid the same amount to see you in your hot pink jumpsuit? Probably not. Back in the day, flying was a commodity — no matter what class you chose — and respectable attire was airline protocol. Here is a list of some first-class do’s and don’ts, along with some suggestions of comfortable yet classy attire. 1. DON’T wear your favorite pair of fuzzy slippers when boarding the plane. 2. DO bring a pair of modest slippers in your carry-on to change into after boarding, or wear a pair of classy flats. Leather ballet flats or boat shoes have the comfort and flexibility without the clash. Here are a few suggestions: – Women’s JCrew ballet flat – Men’s JCrew boat shoe – Modest Women’s Dakota slipper – Men’s Scuff Slipper 3. DON’T wear your favorite Champion sweatsuit or Juicy Couture jumpsuit. 4. DO bring a comfortable outfit to change into after boarding or wear a classy, comfortable outfit to the airport.  Here are a few suggestions: – Women’s Donna Karen jersey leggings – Women’s wrap cardigan – Men’s comfortable pinstripe linen pants – Men’s half-zip sweater These tips may sound silly to the paying customer, but you aren’t the only one flying to your destination today; and you certainly aren’t the only person expecting a comfortable, smooth, less-distracting flight. Happy flying! — Courtney Centeno, account executive
