Thai Vietjet Air does not fly to the United States. It is also not the same company as Vietjet Air in Vietnam. It is a separate, Thailand registered low cost carrier with its own air operator certificate.
That split identity is why the Thai Vietjet Air baggage allowance question trips up so many travelers. Two airlines share a brand and part of a website. Their rules do not automatically match.
Thai Vietjet Air is not the same airline as Vietjet Air
Vietjet Aviation Joint Stock Company is the Vietnamese carrier, coded VJ. It is the one most US travelers have heard of. Thai Vietjet Air, coded VZ, is a different company.
Thai Vietjet is a joint venture between the Vietjet group and Thailand’s Kan Air. It is licensed and operated as a Thai carrier. The two share branding and a booking platform, which is where the confusion starts.
A rule confirmed for Vietjet Air in Vietnam does not carry over automatically. This page treats the two as separate carriers and uses Thai Vietjet’s own figures only.
What we could confirm about the Thai Vietjet Air baggage allowance, and what we could not
We tried the standalone thaivietjetair.com domain first. It did not return a working airline page during this research session. We then checked the Thailand section of the main Vietjet Group baggage information page.
That page exists, but it loads its content through scripts our tools could not read reliably. We cannot state a confirmed carry-on weight for Thai Vietjet Air from that check. We cannot confirm a checked bag weight or fee schedule either, and we will not guess at one.
Our editorial policy is to say so plainly. A borrowed number from a comparison site or an old forum post is worse than no number at all.
What travelers say the carry-on limit actually is
Community reports fill some of the gap the official pages leave open. One reviewer described Thai Vietjet enforcing a combined 7 kg limit. That limit covers the cabin bag and the personal item together, not each one separately.
Several frequent flyer forum threads ask this exact question about Thai Vietjet’s luggage allowance. That alone suggests the limit is not obvious from the airline’s own marketing pages. Treat the 7 kg figure as a traveler report worth planning around, not a number we read on the carrier’s own site.
If it holds, it is stricter than many peers. Most full service carriers allow a cabin bag plus a personal item separately. Many budget carriers do too.
Checked bags on a Thailand based budget carrier
Low cost carriers across Southeast Asia generally sell checked baggage as a paid add-on. It is priced in weight tiers. Buying it online early is almost always cheaper than adding it at the airport.
We expect Thai Vietjet Air to follow that same general pattern. We could not pull its exact weight tiers or prices from the carrier’s own pages when this page was checked. Our guide to how baggage fees work covers that add on structure in more depth.
Run your actual route and dates through our baggage cost tool once fares are bookable. The live booking flow will show real tier pricing where a static page will not.
How Thai Vietjet Air compares with its regional neighbors
Thailand’s flag carrier, Thai Airways, publishes cabin and checked limits in a plain table. So does the Vietnamese sister brand behind Vietjet Air’s own baggage rules. Regional budget rivals like AirAsia and Scoot also spell out carry-on weight in kilograms right on their booking sites.
Thai Vietjet Air is the outlier only because its own figures were harder to pin down remotely. That is not evidence its actual rules are unusually generous or strict. It is a real gap, and it is worth knowing about before you assume the Thai Vietjet Air baggage allowance mirrors any of these peers.
Before you fly Thai Vietjet Air
Check the baggage section shown during your own booking flow. Check it again in your confirmation email, since that reflects the fare and route you actually bought. Weigh your cabin bag and personal item together at home if the combined limit report above applies to your flight.
Shift extra weight into checked luggage rather than risk a gate side repack. Our carry-on size and weight guide explains how combined limits get enforced across carriers generally. That context is useful even where one airline’s own numbers are still a gap for us.
The bottom line
Thai Vietjet Air is a distinct Thai carrier from Vietjet Air in Vietnam. It does not serve the United States. Its own site did not give up a confirmed carry-on or checked bag figure during this research pass.
Traveler reports point to a strict combined 7 kg cabin allowance. Low cost norms suggest paid checked bags priced by tier. Neither is a number we read directly off Thai Vietjet’s own page.
Confirm the Thai Vietjet Air baggage allowance for your specific fare at booking. Treat this page as a starting point, not the final word, until the carrier’s own numbers are reachable again.
