Pack light and pack smart (aka skip the bag-drop line).
"It doesn't matter if you're traveling for two weeks, a month, or a weekend. You can fit everything you need in a carry-on suitcase and a backpack. Remember, laundry exists all over the world, and when is the last time you ever wore everything you packed anyway?
What you pack will vary based on where you're going of course, but my go-to is two pairs of shoes, a couple pairs of jeans, a couple dresses, a sweater or sweatshirt, five shirts, PJs, and five pairs of socks and underwear. Depending where you're traveling you may need extras (like a swimsuit, scarf, rain jacket, etc), but you get the idea.
Oh, and there's no weight limit for carry-on bags. YAY!"
Yeah, some are only 10kg!
There is no step 2.
Enjoy your flight.
