13.5 × 8.5 × 3.75 inEnormous margin against every limit here, and it looks like a normal bag rather than travel gear. Ten litres is a daybag though, not a travel bag.
Iberia allows a cabin bag of 56 × 40 × 25 cm — 22 × 15.7 × 9.8 inches — and weighs it at 10 kg (22 lb), which most US carriers never do. The under-seat item is 40 × 30 × 15 cm.
Fare class: Not distinguished on the hand-luggage page; Economy and Premium Economy both get one 10 kg cabin bag plus a personal item.
Iberia warns in its own words that on busy flights “there may be restrictions on carrying hand luggage weighing up to 10 kg with you in the cabin” — a compliant bag can still be gate-checked, free of charge.
Measure the outside, wheels and handles included — that’s what they measure at the gate.

The anti-theft option that actually fits — slash-resistant panels, locking zips, RFID pocket, and a 13-inch laptop sleeve, all inside United’s width.
Pacsafe’s own site is JavaScript-gated, so this comes from a retailer spec rather than the brand. The 0.2 inches of width margin rests on that number.

Yes — 40 × 30 × 15 cm, or 15.7 × 11.8 × 5.9 inches. It goes under the seat in front of you.
Yes. A standard American 22 × 14 × 9 inch carry-on clears Iberia’s 22 × 15.7 × 9.8 inch limit, though the 10 kg weight limit is the more likely problem.

Of the bags we track, 12 of 16 carry-ons fit the cabin limit and 2 of 25 personal items fit the under-seat limit. All of them are under the weight limit empty.
Manufacturers publish dimensions inconsistently, and a “20-inch” spinner is almost never 20 inches once you count the wheels. Where a brand states dimensions including wheels and handles, that’s the number we use. Where it only publishes the case, we say so on the card. Airlines measure the outside of your bag — wheels, handles, straps and all. Anything marked borderline is down to the gate agent, and remember that a soft bag squashes into a sizer while a hard shell won’t.
