Once you've studied up on Fischbach's concise list of items to avoid while flying, sub in her flight-friendly go-tos. Layering is her top suggestion for ensuring you enjoy a comfortable flight.

"I always try to layer for flights I'm on as a passenger," she explains. "If you must wear a skirt or dress, wear tights underneath, even if it's the middle of summer and you are travelling from Miami to Cancún." Fischbach says she favours cropped trousers when she's flying as a passenger. "J.Crew makes a pair with an elastic waistband that are so comfy you feel like you are in your pj's but still look sophisticated," she says. She also brings her own thick socks for extra warmth for her feet. "I usually bring a lightweight jacket or cashmere hoodie with lots of lightweight layers underneath," explains Fischbach. "I am always cold, so I need lots, but there are those occasions where the aircraft is blazing hot and even I need to cool off." One of her flying staples that offers versatility and an easy way to adapt to the temperature is a big cashmere scarf. "I never travel without that," she says. "A lightweight one for summer and thick one for winter," which is also great if blankets aren't provided on the flight. "It is possible to be comfortable without looking like you just came back from the gym or rolled out of bed."

For those who want to dress up for a flight because you're travelling for business or seated in first class, Fischbach reassures that "dressing up and remaining comfortable isn't as difficult as it sounds." She suggests the outfit formula of a blouse with a sweater and cropped trousers as an easy go-to for travelling for business. "I've seen more and more companies incorporating elastic into the waistbands of many of their slacks," naming Uniqlo as one such brand, "and a flowy blouse can easily hide any evidence of a not-so-fitted waistband." Choosing the right material can also increase your level of comfort." Lots of dressier trousers have a bit of stretch to them now, always a more comfortable choice in any situation," Fischbach notes. She also suggests sheath dresses which work with tights or nylons. "Don't forget blazers to dress it up if you're on your way to a post-flight meeting and maybe a change of heels if flats or loafers don't work for your total ensemble," she says. "And ask your flight attendant if it is okay to hang it in the closet. Who wants added wrinkles? Look your best!"
