Best Underseat Personal-Item Bags That Fit Under the Seat (by Airline Size Limit)

The COSCOOA 17x10x9 backpack is the best overall underseat personal item: it is built to United's strict 17x10x9 slot, so it clears every major US airline at once. Only United enforces a 10-inch width — meet that and Delta, American, JetBlue and Southwest all pass automatically.
