Is London Fog luggage good quality?

It is positioned as budget-to-midrange. Fabric, zips and organisation are solid for occasional travel; wheels and telescoping handles are the parts that wear first under heavy weekly use.

Does London Fog luggage come with a warranty?

Most cases carry a limited manufacturer warranty covering defects in materials and workmanship, but not airline handling damage. Register the case and keep proof of purchase.

Will a 21-inch spinner fit as a carry-on?

Usually yes on major US carriers, provided you do not use the expansion zip. Budget and regional airlines apply smaller limits, so check before you fly.

London Fog Luggage

London Fog luggage aims at the value end of the travel market: fabric softside cases, expandable spinners and matching sets in muted colours rather than technical materials.

That makes them a reasonable choice for occasional travel and family trips. For weekly flying, judge each case on its wheels, handle and warranty rather than on the badge.

What to check before you buy

Carry-on dimensions: Most US airlines cap carry-ons around 22 x 14 x 9 inches including wheels and handles. Measure the case as sold, not the marketing size.
Wheels: Four-wheel spinners glide down aisles; two inline wheels roll better on broken pavement and are harder to snap off.
Softside vs hardside: Fabric cases have outer pockets and squeeze into overhead bins. Hardshells protect fragile items better but crack rather than scuff.
Expansion zips: An expansion gusset is useful going home, but an expanded carry-on often fails the sizer at the gate.
