The Carry-On Only Mindset
Once you start traveling carry-on only, you’ll never go back. No checked bag fees ($35–$70 per bag, each way), no waiting 20 minutes at baggage claim, no risk of lost luggage, and the freedom to move through airports like you actually know what you’re doing. For a weekend trip, there is no reason to check a bag. Here’s exactly how to make it work.

Step 1: Choose the Right Bag
Most airlines allow a carry-on bag up to 22 x 14 x 9 inches and a personal item (backpack or purse) that fits under the seat in front of you. Budget carriers like Spirit and Frontier are stricter — check the specific airline’s policy before you pack, because a bag that’s an inch too big can cost you $50–$100 at the gate.
For weekend trips, a 40–45 liter backpack is the sweet spot. It fits in the overhead bin on every major US carrier, qualifies as a personal item on many flights (saving you even more), and is easier to move through cities than a wheeled suitcase. Popular choices include the Osprey Farpoint 40, the REI Ruckpack, and the Peak Design Travel Backpack — but any well-organized backpack in the right size range works.
If you prefer a wheeled bag, a 20-inch hardside spinner is the standard carry-on size and fits in most overhead bins. Avoid anything marketed as a “carry-on” that’s larger than 22 inches — it will get gate-checked on smaller regional aircraft.
Step 2: Plan Your Outfits, Not Your Items
The biggest packing mistake is throwing in clothes you might need instead of planning exactly what you’ll wear each day. For a three-day weekend trip, you need:
- 3 tops (or 2 if one can be reworn)
- 2 bottoms (pants, shorts, or skirts that mix and match)
- 1 versatile layer (light jacket or cardigan that works for both day and evening)
- 3 pairs of underwear and socks
- 1 pair of shoes you wear on the plane
- 1 pair of shoes in the bag (if needed — often you can skip this)
- Pajamas or sleepwear (a t-shirt and shorts doubles as both)
The key is building around a color palette. Pack tops and bottoms that all work together so every combination creates a complete outfit. Neutral colors (black, navy, white, grey, olive) are your friend here.
Step 3: Master the Toiletries
Toiletries are where carry-on packing gets tricky because of the TSA 3-1-1 rule: all liquids must be in containers of 3.4 oz or less, all fitting in one quart-sized clear bag. For a weekend trip, this is actually plenty of space. Here’s how to make it work:
Buy travel-sized versions of your regular products at Target or CVS — a $1 travel shampoo for a weekend trip is far cheaper than checking a bag. Refillable silicone bottles (sold in packs of 3 for $8–$12 on Amazon) let you bring your own products in reusable containers.
Switch to solid toiletries for frequent travel. Solid shampoo bars, conditioner bars, and soap bars don’t count as liquids under TSA rules. They last longer than travel-sized liquid versions and take up almost no space.
Skip what your hotel provides. Most hotels supply shampoo, conditioner, body wash, and a hair dryer. Check the hotel amenities before you pack — you may be able to leave several items at home entirely.
Step 4: Pack Smart with These Techniques
Roll, don’t fold. Rolling clothes instead of folding them reduces wrinkles and saves significant space. Thin fabrics like t-shirts and workout clothes roll especially well. Reserve folding for stiffer items like dress shirts or blazers.
Use packing cubes. Packing cubes compress your clothes into organized blocks that fit efficiently in your bag. A set of three cubes (roughly $20–$30) lets you separate tops, bottoms, and underwear/socks so you’re not digging through everything every morning. They also make it easy to repack quickly when you’re switching hotels.
Wear your bulkiest items on the plane. Jeans, boots, a heavy jacket — if it takes up space in your bag, wear it on travel day. You can always stuff the jacket in the overhead bin during the flight.
Put shoes in a shower cap or shoe bag to keep the soles from touching your clothes. Shoes go along the bottom edge of your bag where they don’t compress clothes in odd shapes.

- Travel documents, wallet, keys
- 1 reusable tote bag (for beach, day trips, or grocery runs)
- Any medications
Budget Airlines: Read the Fine Print
Spirit, Frontier, and Allegiant charge for carry-on bags that go in the overhead bin — only the personal item (under-seat bag) is free. If you’re flying one of these carriers, size your bag to fit under the seat (typically 18 x 14 x 8 inches or smaller) to avoid the carry-on fee, which can be $50–$75 if you pay at the gate. A small backpack or daypack that slides under the seat is your best friend on budget airlines.
Even with this restriction, a well-packed under-seat bag can handle a two or three day trip. It forces you to pack only what you truly need — which turns out to be less than you think.
