Hello I'm flying United Airlines, early Sunday out of California from what is called Ontario airport (ONT) to Trinidad & Tobago, with a layover in Houston (IAH) and I'm concerned about the size of my laptop bag. If I'm reading it correctly, the new limits are 17" for the length; 10" for height; and 9" for depth. The length and depth of my laptop bag fit the new standards, but the height is just over 12". How strictly is this being enforced? Also any one with specific experience with this at the ports I'll be visiting, is welcome to comment.
Also I have read the other post on this site regarding the new rules, but that post really didn't capture individual reactions as to how the new rules were being enforced lately.
