Which bags fit which airline, and the battery, film and tripod rules that actually catch photographers out at the checkpoint.

Pick your airline for the full list with fit margins. The standout is the Think Tank Retrospective 7 V2.0 — the only camera bag here that clears every US carrier, United included.

Drop this into any bag you already own and it becomes a camera bag. Which means you can choose your bag purely on whether it fits your airline, then make it carry gear.
The commuter-sized sling. Small enough to pass as a genuine extra bag alongside a backpack on most carriers, and it fits every personal item limit here.
Peak Design serves its specs via JavaScript we could not fetch, so these dimensions come from retailer listings and are approximate. Verify on peakdesign.com before buying to a tight limit.
The standout. This is the only camera bag in the list that clears every single US airline personal item limit, United’s brutal 17 × 10 × 9 included. If you fly a lot of different carriers and want one bag that never gets questioned, this is it.
The cheapest safe answer. Clears every sizer on every airline, costs about twenty dollars, and carries a single body and a couple of lenses without fuss.
The same idea as the Tenba insert but with Peak Design’s divider system and clip-in attachment points. Turns any compliant bag into a camera bag.
The bigger sling. It takes a 13-inch laptop alongside a working kit, which makes it a genuine one-bag personal item for a day of shooting.
Only a fraction of an inch under United’s 17 × 10 × 9. Dimensions are from retailer listings rather than the manufacturer.
The best backpack for a strict personal item limit. Only 5.5 inches deep, takes a 16-inch laptop, and clears the 18 × 14 × 8 budget-carrier box with real margin.
That 17-inch height is measured with the rolltop NOT extended. Roll it up and you break the fit.
The budget camera backpack that still fits a strict personal item box. It isn’t built like a Think Tank, but it’s a third of the price.
Swings round to your front for lens changes without taking it off, and includes an all-weather cover — which the Peak Design slings don’t.
Misses United’s personal item limit by about a third of an inch on height. Fine everywhere else.
A messenger that doesn’t look like a camera bag, with a top flap that genuinely opens fast. Popular with photographers who’d rather not advertise what they’re carrying.
Adventure-photography build with a proper suspension system and a modular core-unit interior you buy separately.
Misses a strict 18 × 14 × 8 sizer by about a third of an inch on height. Soft-sided, so usually fine.
The bigger PRVKE. Expands to 35 litres via the rolltop and stays remarkably slim front to back for the capacity.
Half an inch over a strict personal item sizer — and that’s with the rolltop down.
Narrow, tall and deep — a shape built entirely around carrying long glass upright. Under ten inches wide, which is rare for a bag holding this much.
| Capacity | Carry-on | Checked |
|---|---|---|
| Up to 100 Wh | Yes | Only inside the device |
| 101–160 Wh | 2 spares, needs approval | Inside the device only |
| Over 160 Wh | Not allowed | Not allowed |
Spare batteries are carry-on only, always. The trap is gate-checking — if they take your bag at the door, pull every loose battery out first and keep them on you.
Terminals have to be protected: retail packaging, tape over the contacts, or a case.
In practice this only bites on V-mount and cine packs. Every mirrorless and DSLR battery you own is 10–30 Wh, nowhere near the limit.
Don’t send film through a CT scanner. Kodak Alaris warns the newer checkpoint machines can fog undeveloped film in a single pass — smoky blacks, shadow detail gone. Even ISO 100 isn’t safe.
Officers are trained to hand-check roll film, movie film and single-use cameras when you ask. Keep it separate and reachable, say something before screening starts, and allow ten minutes.
Checked bags are worse, not better. Never put film in one.
No — assume it counts as your personal item everywhere.
Delta lists "camera bag" among acceptable personal items, meaning it qualifies as your one item rather than being an extra. American’s list of things that don’t count against your allowance covers diaper bags, medical devices, strollers and car seats. Camera gear isn’t on it.
The "cameras fly free" folklore traces back to old policies that named cameras as an example. It hasn’t been a real exemption in years.
Travel tripods usually pass in carry-on, subject to your airline’s size limit and the officer’s call. Full-size rigid-leg tripods and monopods draw secondary screening and are easier checked.
Power banks count as spare batteries, so carry-on only. Several carriers added in-flight rules in 2026: Southwest allows one, kept visible and out of the bin; American allows two under 100 Wh, accessible, and you can’t charge them from aircraft power.
Drone packs follow the same watt-hour tiers. Consumer drones sit well under 100 Wh; cinema drone batteries can hit the 101–160 Wh tier and need approval.
Yes. Assume it counts as your personal item on every US carrier. Delta lists "camera bag" among acceptable personal items, which means it qualifies as your one item rather than being an extra. American’s list of items that do not count against your allowance covers diaper bags, medical devices, strollers and car seats — camera gear is not on it.
Spare batteries must go in your carry-on, always. Batteries installed inside a device may be checked if the device is switched off and the terminals are protected, but loose spares are prohibited in checked baggage. Batteries up to 100 Wh need no approval; 101–160 Wh allows two spares with airline approval; anything over 160 Wh is banned outright.
CT scanners can. Kodak Alaris warns that the newer CT checkpoint machines can fog undeveloped film in a single pass, and that even ISO 100 is not safe. TSA officers are trained to hand-check roll film, movie film and single-use cameras on request — ask before screening begins. Never put film in checked baggage, where the doses are far higher.
Travel tripods generally pass in carry-on, subject to your airline’s size limit and the officer’s discretion. Full-size rigid-leg tripods and monopods draw secondary screening and are usually easier to check.
The Think Tank Retrospective 7 V2.0 at 13.5 x 9.5 x 6 inches is the only camera bag we track that clears every US airline personal item limit, including United’s 17 x 10 x 9. A camera cube insert dropped into a bag you already own is the other reliable route.
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.
