How we research.

Our evidence ladder

1. Official rules and specificationsAirlines, manufacturers and programme terms anchor mutable facts.
2. Cross-checked merchant evidenceListings help confirm availability, price and current variants, but do not override the manufacturer.
3. Repeatable first-hand testingOnly content with an explained method, original observations and evidence is labelled a review.

How a shortlist is built

Every commercial guide starts with one decision boundary—such as a firm price ceiling, cabin-fit requirement or trip type. Products must have a live India listing on the research date. We record only visible evidence, separate cabin and check-in use cases, identify missing specifications and explain the trade-off behind every selection.

How products are ranked

Fit for the stated use case comes first, followed by evidence quality, empty weight, construction, warranty, failure-mode signals and value. Discount percentage, sales rank and commission rate are excluded from the editorial score.

Airline-rules methodology

Cabin-baggage policy is treated as mutable operational evidence. We record the visible rule from the airline’s own current page, retain the official link and a checked date, and normalise exact side dimensions into a trolley-style height × width × depth order for comparison. We do not convert a combined-dimension limit into invented side limits. Where official pages conflict, both statements remain visible and the traveller is directed to the ticket, booking or airline; we do not average, rank or silently reconcile them.

The conservative common-fit frame is calculated as the smallest height, width and depth found across the exact published envelopes reviewed. It is a comparison aid, not a guarantee. Product compatibility is published only when the exact model variant’s complete exterior dimensions—including wheels and handles where specified—and empty weight can be tied to reliable dated evidence.

What we do not claim

A research-based comparison is not a durability test. We do not infer long-term wheel, zip, handle or shell performance from merchant descriptions or star ratings. A page will be labelled a review only after repeatable first-hand testing with original observations and evidence.

Corrections and updates

Airline rules are scheduled for monthly review and carry a visible checked date. Product pages show when price or specification evidence was last verified and when the editorial analysis changed. Material corrections update the page rather than silently preserving an outdated claim.
