How CarryFits gets its numbers
Every baggage size, weight and fee on this site is copied from the airline's own published page; every item rule from TSA's own entry for that item. Each number is stored with its source URL and the date we last read it, and both are printed beside it. This page says exactly how that is done, what the labels mean, and where the raw data lives.
Airlines
20
19 carry-on limits and 19 personal-item limits read directly from the carrier's own page ("verified"); 1 and 1 respectively from an official-domain snapshot cross-checked elsewhere ("reported — re-verify"). 1 carrier is kept after ceasing operations, labelled, because the bags bought to meet its limits still exist.
TSA item rules
60
60 of 60 carry a direct link to that item's own entry in TSA's "What Can I Bring?" list. Verdicts are worded within what the source says; anything beyond it is marked as a note, not as a rule. Where a checked-bag limit is the FAA's rather than TSA's — aerosols, spare lithium batteries — we cite FAA PackSafe instead of putting the number in TSA's mouth.
Cruise lines & lists
1 & 4
Cruise prohibited-item rules come from each line's own policy page. Lines differ from each other more than airlines do, so a rule from one ship is never presented as a rule for another.
The four rules we hold ourselves to
1. A number without a source does not go on the page. If we cannot reach an official statement of a limit, the field stays empty and says so. "No published size limit" is a real finding about that airline, not a gap in our research — and it is not the same as a generous limit.
2. The date travels with the number. Baggage policies change without announcement, so a figure is only as good as the day it was read. Every page prints when it was checked, and the source link is there to be clicked before you fly.
3. We do not launder other people's guesses. Most pages that rank for these questions restate each other. When a carrier's site blocks automated reading we say "reported — re-verify" rather than promoting a second-hand number to a verified one.
4. We describe the rule, not your outcome. The checker compares published dimensions; it cannot model a soft bag's give, an unusually strict gate, or an agent's discretion. Where the arithmetic and the checkpoint can disagree, we say so on the page rather than in the small print.
Raw data
The same database the pages render, as JSON, with the source URLs and dates intact:
- /data/airlines.json — 20 carriers, carry-on / personal item / checked segments, weights, fees, verification status, source URL, last-checked date.
- /data/tsa-items.json — 60 item rules, carry-on and checked verdicts, notes, tsa.gov source URL, last-checked date.
Reuse is fine. If you cite a number, link the page you took it from so your readers can reach the official source behind it.
Corrections
Found a number that is wrong or out of date? Email support@carryfits.com with the airline or item and where you saw it. A human reads every message. A correction changes the data file, which changes every page that renders it, and the checked-on date moves with it.
Common questions
Where do CarryFits numbers come from?
Every size, weight and fee on this site is copied from the airline's own published page, and every item rule from TSA's own "What Can I Bring?" entry for that item. Each one is stored with the source URL and the date we last read it, and both are printed next to the number on the page. We do not restate other blogs, and we do not fill gaps from memory.
What is the difference between "verified" and "reported — re-verify"?
"Verified" means we read that number on the carrier's own page and the link next to it goes to that page. "Reported — re-verify" means the carrier's page blocked automated reading and the number came from an official-domain snapshot cross-checked against other sources — good enough to show, not good enough to call verified. A field we could not source at all is left blank and labelled, never guessed.
How does the fit checker decide whether a bag fits?
It compares your three measurements against the airline's three, largest side to largest side, because a bag can be turned. It does not model compression: a soft bag may squeeze into a sizer that this arithmetic calls too big, and the gate agent's sizer is the final word either way.
How old are these numbers?
Every page prints the date its numbers were last checked. The airline database was last fully reviewed on 2026-07-02. Airlines change baggage rules without notice, so the source link beside each number is there to be clicked before a trip, not for decoration.
Can I reuse this data?
Yes. The airline database is published as JSON at /data/airlines.json and the TSA item rules at /data/tsa-items.json, with the same source URLs and dates the pages show. If you cite it, please link the page you took it from so readers can reach the underlying official source.
What if a number is wrong?
Email support@carryfits.com with the airline or item and the page you saw it on. A human reads every message. Corrections change the data file, which changes every page that renders it, and the checked-on date moves with it.
