Quick Answer
The best carry-on combo is the Travelpro Maxlite 5 21" (~$157) as your overhead carry-on + Herschel Retreat Backpack 17L (~$60) as your personal item. Total weight under 8lbs, handles 1-2 weeks of travel, and fits every major airline's requirements.
Maximize Your Free Carry-On Allowance
Every airline allows two free bags in the cabin: one carry-on (overhead bin) and one personal item (under the seat). Most travelers underutilize their personal item — they bring a small purse or backpack that could be twice the size. Getting this right means packing for a 5-day trip without checking a single bag.
The winning combo: Travelpro Maxlite 5 ($157) as carry-on + Inateck 17L laptop backpack ($49) as personal item. The Travelpro holds your clothes and toiletries; the Inateck holds your laptop, headphones, power bank, and in-flight essentials. Both fit within standard airline dimensions with room to spare.
Backpack alternative: Osprey Farpoint 40 ($111) overhead + a slim crossbody or small backpack under the seat. This works if you prefer backpack travel over rolling luggage.
Personal Item Size Rules by Airline
| Airline | Personal Item Max Size |
|---|---|
| Delta, United, American | 18"×14"×8" (under seat) |
| Southwest | Must fit under seat — no hard dimensions |
| Spirit | 18"×14"×8" — enforced at gate |
| RyanAir (Europe) | 40×20×25cm — very strict, measured at gate |
Why the Right Combo Matters
Most airlines allow one carry-on (overhead bin) and one personal item (under seat). Maximizing both means you can travel for weeks without checking a bag. The key: your carry-on handles clothes, your personal item handles daily essentials — laptop, chargers, snacks, documents, headphones.

What counts as a personal item vs carry-on?
Personal item = goes under the seat in front of you. Usually limited to about 18"×14"×8" depending on airline. Carry-on = overhead bin, typically up to 22"×14"×9". You're allowed one of each.
Can I bring a backpack AND a carry-on?
Yes. Your backpack is your personal item (under seat), your rolling carry-on is your carry-on (overhead bin). This is the standard travel setup for carry-on-only travelers.
What's the best personal item bag to pair with a carry-on?
The Inateck 17L Laptop Backpack ($49) for function, or the Baggallini All Day Crossbody ($65) if you want something that transitions from airport to city without looking like travel gear.
Can I bring a backpack and a carry-on?
Yes — that's exactly the system. Carry-on in the overhead bin, backpack under the seat in front of you. Both are included in your base fare on most US carriers (Spirit and Frontier charge for the overhead carry-on). The Travelpro + Inateck combo maxes out the allowance without either bag looking overstuffed.
