Originally posted by tibbitts Yes, thanks, I did look at them but I'm pretty sure the 450 models would incur scrutiny as a "personal item" and not fit under a seat... not sure about the 350. I'm hoping someone will have personal experience.
I typically fly 3-4 times a year. I use a standard size rolling carry-on and a backpack the same size as the 350.
I have never had an issue with Hawaiian, Alaska, Delta, American, JetBlue, WestJet, Southwest, or even United. On the smallest turboprops to the smaller cities, if they are overloaded or the overhead bin wonʻt fit my rolling carry-on, then theyʻll put that one in the cargo hold for free. If I get a bulkhead seat or there is some obstruction under the seat in front of me (rare), then Iʻll just put my backpack in the overhead.
There is usually a 25 lbs. limit per carry-on, so just make sure you donʻt bring gold bars in your backpack. With more and more self check-in at kiosks these days, if you act as if your backpack is heavy, they will ask you to weigh it and may have you transfer some of the weight to another bag.
I sincerely think youʻll be fine with any of those Lowepro models (including the 450) I had suggested and itʻs a matter of deciding how large of a backpack you want or need in terms of weight on your back and what youʻre bringing with you.
