What to Wear on a Long-Haul Flight: Pants & Comfort Hacks
Seriously, pants can make or break a flight!
Happy after a lovely flight from the Faroe Islands!
Last update: April 2026
There’s always that moment mid-flight where you regret your outfit.
Too cold, too tight, or just… wrong. Here’s what actually works.
So it all started with our friend who was planning a trip to Japan and asked us what pants we usually wear for a long-haul flight. And we realized she’s probably not the only one wondering about that — so we decided to write an article about it!
You’ve booked your ticket, packed your bags, and now the eternal question hits: what do I wear on the plane?
It sounds silly until you’re 36,000 feet up, crammed between a snorer and the armrest, regretting every clothing choice you made. We’ve flown everywhere from New Zealand to the Arctic — and trust us, the wrong outfit can ruin a flight.
Here’s our guide to airplane outfits: personal lessons, science facts, and gear that actually makes long-hauls less miserable. Check our flying essentials here!

🧳 Field Notes
What we wear: Loose joggers or thick leggings, always with warm socks. Hoodie + tee combo on top.
What we avoid: Jeans. Skinny anything. Looking stylish, because it really doesn’t matter.
Packing hack: Take a mini deodorant, a bit of lotion and a toothbrush with you. You’ll feel so much refreshed after sleeping!
Mistake we made: Wearing thin leggings on a 14-hour flight (as part of a 30 hours trip). Freeezing even with a blanket!
Arrival tip: Book airport transfers or first-day tours on Viator — land comfy, explore fast.
What should you wear on a plane for long-haul travel?
What you wear on a plane matters more than people think (at least it does for us!), especially on long-haul flights where comfort, temperature changes, and hours of sitting all add up. The best choice is usually a simple, layered outfit: breathable base layers, something warm you can add or remove easily, and relaxed clothing that doesn’t restrict movement or circulation (comfy pants, people!). We keep coming back to this approach because it makes the entire travel day easier—security, boarding, sleeping, and landing all feel less annoying when you’re not fighting your outfit.
The goal isn’t to look “airport stylish” (that dies after hour 6 anyway), but to arrive in the best state possible, not overheated, frozen, or regretting your jeans decision halfway across the Atlantic.
Pants to avoid on a long-haul plane
Alright, so let’s start with our friend’s question (we won’t mention her name…): the pants!
Let’s be very glamorous here: In the sky, you’re bloated, your skin is dry, and you go from shivering to sweating. No, you don’t have a virus (we also won’t mention any name either…); you’re just on a plane!
So basically, you need to be extra comfy, snuggly, cozy, so you can hopefully relax and maybe sleep a little!
Did you know?
Flying changes your body:
Air pressure = more bloating. Gas expands at altitude (yes, that’s why you fart more). Tight waistbands feel like torture.
Cabin air = desert dry. Humidity drops to Sahara levels, which is why your skin cracks and your nose feels weird.
Temperature rollercoaster. One minute you’re shivering under blasting AC, the next you’re sweating because the cabin is too warm.
Pic: With such a landscape (Greenland ice sheet), you forget any discomfort!
So, what pants should you avoid when flying?
Jeans
Stylish? Sure. Comfortable? Not at altitude. The stiff waistband + bloating = nope. Even oversized jeans will still be a constraint when sitting for hours.Thin leggings
Good for yoga class, but in-flight you’ll freeze. Cabin temps dip and thin fabrics don’t help. Even with a blanket, it gets cold after a few hours. That being said, there are some types of leggings that can work. Keep reading!Tight joggers
Waistbands that dig in will make the pressure bloat worse. And make sure they don’t go up when sitting, the cold will get your ankles too!

Pants we actually recommend
Our go-to bottoms for flying long haul (tested on too many red-eyes):
Yep, Eli is wearing leggings in Svalbard at -35ºC. Bravo!
Comfy joggers — loose, soft, not too tight around the waist and not too short. You can even size up if needed! Something like these joggers.
Thicker leggings — lined or thermal versions keep you cozy without bulk. Avoid fleece lining, as you might overheat, and prefer natural fabrics such as merino leggings. If they’re a base layer, make sure they’re not transparent! I take mine everywhere, from Iceland to Norway.
Wide-leg travel pants — airy, comfy, and stylish enough to walk straight into a café after landing. Even more chic with a travel set. They’re great if you're flying somewhere relatively warm (like Portugal or Barcelona), so you can also wear them during your trip.
Socks (not pants, but important) — compression socks help reduce swelling and keep circulation moving. Or thick socks (“house” type) to wear when you take off your shoes.
Oh, and comfortable clothes help, but travel insurance is what actually lets you relax once you board! Get 5 to 15% off with our travel insurance partner HeyMondo.
Don’t forget the top half
That’s easy for Mac: he doesn’t wear clothes.
Your pants can only do so much. The magic is in layering:
Hoodie (with a real hood) — block out cabin lights, cover your face to sleep, and skip the scratchy airline blanket. Something like this, but of course much cooler if you bought it on one of your fabulous trips!
T-shirt underneath — when the cabin suddenly heats up or you land somewhere tropical (or with crazy heating on in the airport) you’ll be glad you can peel down to a tee.
Big scarf/blanket — doubles as a shawl, pillow, or actual blanket. Travel scarf here.
Think onion strategy: add and shed layers as the cabin mood swings.
Penguin Trampoline tip:
Up north, don’t expect a jet bridge. Many Arctic airports are literally snow strips, and you’ll walk straight off the plane into the elements. If it’s –30°C and you’re in thin leggings, well… consider it a very brisk welcome to the Arctic. Layer up before you land!
Not clothing, but noise-cancelling headphones are the closest thing humans have to a personal force field. On planes, trains, buses—anything that rattles, hums, or hosts a crying baby — they turn chaos (and annoying engine sound) into a gentle hush so you can actually enjoy your music, podcasts, or glorious silence. We travel with ours everywhere; they’ve saved more sanity than coffee ever could. If you want the same peace bubble, here’s a pair we recommend (or cheaper version).
It’s an investment, but if you travel a lot and enjoy music (and peace), it’s totally worth it.
Oh, not clothing either, but make sure you activate your travel eSIM if there’s no free roaming where you’re going. Don’t have one? Get a travel eSIM in seconds with Airalo.
Fun (and slightly gross) plane facts
Jake, happy to get some very fresh air in Kiruna, Lapland
Yes, your farts get worse on planes. Cabin pressure makes gas expand 30% more than normal. Tight waistbands = extra regret.
Why you cry at movies. Low oxygen + dry air + stress makes even cartoons feel like Oscar-worthy tragedies.
Why it’s often freezing. Airlines keep cabins cool because passengers faint less at lower temps.
Why it’s sometimes boiling. Warm cabins save fuel. That’s when your t-shirt earns its spot.

FAQ: What to wear on a long-haul flight
Are jeans good for flying?
Not really. The waistband digs in as your stomach expands. Comfier options: joggers, leggings, or wide-leg pants. That being said, Jake does it. Yuck.
What tops should I wear on a plane?
Layer up: start with a t-shirt, add a hoodie or sweater, and keep a scarf handy. Flexibility is key.
Should I wear compression socks on flights?
Yes. They reduce swelling and help prevent circulation issues, especially on flights over 4 hours.
Are leggings okay for long flights?
Yes — but thicker, lined ones are better. Thin leggings can leave you shivering.
What’s the one thing not to forget?
Warm socks. Cold feet will ruin your flight faster than turbulence.
Here is our personal travel playlist:
Flying isn’t glamorous anymore, but it doesn’t have to be torture either. Jeans and tight waistbands are out. Joggers, thick leggings, wide-leg pants, compression socks, and layers on top are in.
Bring a hoodie you can hide in, a t-shirt for when things heat up, and a scarf that doubles as a blanket. Trust us — your future self (and your seatmate) will thank you.
