I still feel like I have no idea what the right answer is. For example, Delta says:
SO WHAT EXACTLY IS ALLOWED?
Approved Personal Items
1 purse, briefcase, camera bag or diaper bag
or 1 laptop computer (computers cannot be checked)
or 1 item of a similar or smaller size to those listed above
"Similar size" No actual measurements listed.
As explained above, it's going to be at the discretion of the gate agent and/or check in agent. If you don't know how large a standard briefcase or diaper bag are, look on Amazon.
The general rule is your personal item must fit fully under the seat in front of you.
