My regular underwire bras don't cause a problem, but my nursing bras with underwire ALWAYS set the detectors off. I had to switch to always wearing my cotton "sleep" bra when I traveled while I was nursing, which was not a great look, let me tell you... So SOME underwire bras do cause problems, but I think most underwire is actually plastic.

I also avoid belts, barrettes, boots... Agree with slip-on shoes and layers.

100s, if not thousands, of flights in underwire bras without trouble. None of my friends have had any troubles either, or else I would have definitely heard!

This will sound kind of random, but I always wear long pants on transatlantic flights. One time I wore a pair of calf-length yoga pants and froze because there was an air conditioning vent under my seat.

I have never had a problem with an underwire bra/metal detector.

What type of travel are you doing (business/pleasure?) I have only traveled for pleasure, but my favorite travel shoes of all time are Dansko clogs. Very easy to slip on/off for security, very comfortable to walk in, both at the airport and around town once I arrive at my destination. Word of caution, whatever shoes you choose, be aware that your feet may swell during air travel. Do not bring shoes that are already a bit tight.

Wait, have you never flown before? (And for the record, I have never been stopped for an underwire bra!)

I wear a high quality sports bra on flights. Underwire bras don't go with metal detectors!

I recently traveled to Europe and decided to wear a dress with leggings. I added a belt to the dress but did not put it on until after security. I also had a little sweater and slippers for the plane (the kind that look like mocassins). I was much more comfortable than the times I chose to wear jeans or pants!

I travel all the time. When not for business, I just wear Lululemon things (my pants are not tight) with layers. For business, I just wear comfortable pants, a tee and some sort of blazer. Flights can be freezing or scalding. The warmest flight I've ever been on was one from Minneapolis and it was freezing outside.

Slip on shoes are nice for security, but only take them if you plan to wear them on the actual trip and not just to the airport. Although I'm a total shoe whore (I can't believe I just said that), having extra shoes you don't wear on a trip is a pain.

Bring a shawl or pashmina. There is no chance in hell I'd ever use an airline supplied blanket. Lots of people like those neck pillows and they are pretty easy to carry on board.

Drink more water than you can imagine. Planes are so dry. I usually buy a big bottle of water after security so that I am not dependent on flight attendants for liquids.

Layers! Make sure that you are comfortable in front of strangers in whatever the lightest layer is. In other words, make your inner layer something that isn't too snug or sheer. It can get brutally hot or bone-chilling cold, and might do both on the same flight.

Slip on shoes help, both for getting through security and for when you wish to get up and use the toilet. Ideally you can walk--possibly even run--a mile or more in them. Sometimes your gate is a long ways away.

Warm socks. If you aren't wearing them with your shoes, definitely pack a pair in your carry-on.

A maxi dress could be awesome for travel. Otherwise make sure your pants are comfy and have some stretch. Just don't wear sweats, especially ones with words on your tush.

A pashmina, shawl or large scarf is a nice thing to have. Doubles as a blanket.

Something that doesn't wrinkle, or hides the wrinkles well. Something that resists or hides stains, as you never know what might get spilled on you.

Pack a tube of hand/face lotion in your carry-on. The air is very dry, and lotion can make you feel so much better.

On transatlantic flights I've always gotten a pillow and blanket - is this not the case on all airlines?

Comfortable layers, socks and slip on shoes (or else be like my husband last week, running through the airport barefoot as delays caused him to not have enough time to tie his boots between flights). Skip the belt if you can. You will likely not get a pillow or blanket.

Do not wear a lot of jewelry or clothing with metal. Do wear layers -- often there are huge temperature swings on flights.

Wear layers and bring socks. I like to carry a warm pair in my carry-on as my feet always get cold on long flights. They'll give you a pillow and blanket.

What would you NOT wear? From security to the actual transatlantic flight, what tips can you offer? I have heard easy to slip off shoes are important.
