I have been traveling frequently for business and personal for years. I never like to check my bags, so I usually have my one overhead and one personal item for under my seat. The Delsey Underseat bags are my go-to for personal items. They fit my laptop and all toiletries. There is also a strap that connects to my roller bag and keeps everything easy when rolling through the airport. If I have a business trip in a big city with lots of walking, I use it for my computer bag to save strain on my shoulder.
Normally $140. You can snag one for $32.99 with free shipping today.
