Samsonite Omni 2 vs Omni PC: Which Should You Buy?

Samsonite has been making the Omni PC since 2015. It became one of the bestselling hardside luggage lines in the US on the strength of its 100% polycarbonate shell, its TSA locks, and a price point that sits between budget ABS bags and premium brands like Away and Briggs and Riley. The Omni 2 arrived later as a design refresh, available exclusively through Amazon, adding dual spinner wheels and a USB port to the carry-on version but removing the TSA lock from the carry-on in the process. The difference between the two is smaller than most comparison articles suggest and larger than the product photos make it appear. Here is a complete breakdown of both bags across every spec and feature that actually matters when you are trying to decide between them.

Head-to-Head: Omni PC vs Omni 2

Shell Material and Durability

The Omni PC uses 100% polycarbonate throughout, which is injection-molded under pressure to produce a thicker, more rigid shell than most competing hardside bags at the same price. The micro-diamond texture is functional rather than decorative: the raised pattern absorbs surface contact and disperses scratching forces across a wider area, which is why Omni PC bags that have been checked dozens of times tend to show scuffing rather than deep gouges. The Omni 2 uses polycarbonate in some configurations and ABS in others, depending on the variant. Amazon’s listing for the carry-on references a “polycarb brushed-texture shell” while the product details list “Polycarbonate (PC)” as the material. Either way, the shell feels slightly lighter and more flexible than the Omni PC, which is a trade-off between weight and rigidity.

TSA Lock

This is the single most important practical difference between the two bags and the one most frequently misunderstood by buyers. The Omni PC has a TSA-approved combination lock on every size including the 20-inch carry-on. The Omni 2 does not include a TSA lock on the carry-on, only on the checked sizes. If you regularly place valuables in your carry-on or travel to destinations where securing your overhead bag matters, this is a deciding factor in favor of the Omni PC.

USB Power Hub

The Omni 2 carry-on includes a built-in charging system compatible with external battery packs. You insert a portable charger into the internal USB hub and charge devices through the exterior port without opening the bag. The Omni PC has no USB port on any size. For frequent flyers who run low on battery during connections and prefer not to hunt for airport outlets, the Omni 2 carry-on solves a real problem. For everyone else, it is a feature that rarely gets used enough to justify the trade-off of no TSA lock.

Wheel System

The Omni PC uses a single-wheel spinner at each corner, four wheels total. The Omni 2 uses a dual-wheel cluster at each corner, also four mounting points but two wheels per point. Dual spinners distribute the bag’s weight across a slightly larger contact area, which makes the bag feel more stable at high rolling speeds and reduces the wobbling that can happen with single spinners on an uneven floor. In practice, both systems roll smoothly across airport tile. The difference is most noticeable when the bag is fully packed and you are moving quickly.

Weight Comparison

The Omni PC carry-on weighs 6.1 lbs empty. The Omni 2 carry-on weighs 7.5 lbs empty. That is a 1.4 lb difference, which matters on routes where airlines enforce a strict carry-on weight limit. Most US domestic airlines do not weigh carry-ons, but budget carriers and many international routes have limits as low as 15 to 17 lbs for the overhead compartment. Starting 1.4 lbs heavier on the carry-on leaves less room for what you actually pack.

Interior Organization

Both bags use a similar two-section interior with cross straps on one side and a zippered mesh divider on the other. Neither has dedicated laptop sleeves, compression pads, or specialized pockets. The Omni 2 24-inch medium has elastic tie-down straps and a lining pocket for small items in addition to the mesh divider. If more advanced interior organization matters, both bags are best paired with packing cubes. See our guide to the best compression packing cubes for options that fit both the Omni PC and Omni 2.

Who Should Buy Which

Carry-On Size Guide

Both the Omni PC 20-inch and the Omni 2 carry-on are sized to meet most major US airline carry-on restrictions, but the dimensions differ slightly and this matters on stricter routes.

Airline	Carry-on Limit	Omni PC 20″ (22″x15″x9.5″)	Omni 2 (22″x14″x9″)
American Airlines	22″x14″x9″	Borderline — 15″ width may be flagged	✓ Exact fit
Delta	22″x14″x9″	Borderline	✓ Fits
United	22″x14″x9″	Borderline	✓ Fits
Southwest	24″x16″x10″	✓ Fits	✓ Fits
Most international carriers	21.5″x15.5″x7.9″	May not fit	May not fit

In practice, most US airline gate agents do not measure carry-ons unless a bag is visually oversized or there is limited overhead space. The Omni PC 20″ has been used as a carry-on by thousands of domestic travelers without issue. For international routes or budget carriers where carry-on size is strictly enforced, the Omni 2’s slightly smaller profile is an advantage.
