Is the LuggeX EX-Lite 28" good for frequent flyers?

Not ideal. ABS cracks more readily than polycarbonate or polypropylene under rough baggage handling, and the bag is heavy empty. It fits occasional travelers better than weekly flyers.

How big is the 28-inch EX-Lite compared with a carry-on?

It is a large checked bag at 28 x 19.1 x 12 inches, roughly 106 L. That is well beyond carry-on limits, so it must be checked on every airline.

Does the EX-Lite have a TSA lock?

Yes. A TSA-approved combination lock is built into the shell, so security staff can open it without breaking it.

Can I pack more by expanding it?

Yes. The expandable zip section adds depth when you need it, useful for souvenirs on the return leg. Expand it before weighing the bag, since the extra space counts toward airline limits.

What is the empty weight?

9.5 lb. That is heavy for a 28-inch ABS case and eats into airline weight allowances before you pack anything.

Is ABS durable enough for checked luggage?

It handles normal trips but is more prone to cracking and scuffing than polycarbonate or polypropylene. Expect visible wear on the black shell over time.
