Due to the baggage restrictions by Allegiant Air, I am pretty sure I can't declare my 30L backpack as the "free personal item" (16"x15"x7"). Nonetheless, I may be able to compress the backpack along with some clothes into an appropriately sized parcel. I have actually never seen someone doing this, therefore I am asking if this may lead to check-in difficulties.

  • 16x15x7 of what? cm? ft? in?

    @pnuts: I mean put it in the question, not the comment.

Not a problem. I've taken all sorts of weirdly shaped items in the past (including a full stereo system in shopping bags!), and as long as you meet their criteria, ie:

  • no explosives or other banned substances
  • no blades or other banned items
  • fits their width x height x depth restrictions
  • weighs less than their weight limits

then you'll be fine taking it aboard.

Saying that, measure the backpack first - I'm taking a 30L pack on a flight again today and it's actually small enough to fit into most airlines' carry-on limits.

EDIT: Now that their site is working for me, I can see there's actually a FAQ about this on that link above:

I carry a big purse. Will I be charged a fee to bring that on board or can it count as my personal item?

Which sorta covers your question - basically will something large be too large? And they respond..

All carry-on and personal items must fit within Allegiant’s luggage dimensions and may be verified prior to boarding. Please measure your bags carefully, including exterior wheels, pockets, and decoration.

Personal items which do not fit completely underneath a seat may be considered a carry-on bag and passengers will be charged accordingly. Excess and oversize bags may be gate checked.

The personal item must not exceed exterior dimensions of 7 in. x 15 in. x 16 in. (17.8 cm x 38.1 cm x 40.6 cm) and must be placed under the seat. The carry-on bag’s exterior dimensions must not exceed 9 in. x 14 in. x 22 in. (22.9 cm x 35.6 cm x 55.9 cm).

So as expected, as long as your 'personal item', whatever it is, meets their requirements, you should be fine.

  • The height of my 30L is (with or without handles) about 2 to 3 inches over the limit of 16 inches. And I expect the low-cost carrier to measure precisely because they want me to pay an additional 50$. Dec 12, 2014 at 0:10
  • @user2084795 that's a nuisance, my pack must be more compact. in that case, yeah, my answer still applies - compressing it or whatever into any shape is fine, as long as you meet their luggage restrictions and requirements.

  • @pnuts he's mentioned the site above with limits of 15x7x16? are you getting it from somewhere else?

    Oh I misread your comment as that measurement being for personal items. I follow now :)
