Choose from Thailand's five home carriers or 15 other airlines on Thai routes, then pick where the bag will travel. Wheels, handles and packed-out pockets all count, and a soft bag still has to fit the frame.

How we check
A product list tells you what's popular. We tell you what fits.
-
01
One source: the airline itself
Every limit is taken from the carrier's own baggage page, never from forums or comparison sites. We link to that page so you can check it too.
-
02
Checked again, and dated
Allowances shift with fares and add-ons, so each rule set shows the month we last compared it with the airline's page.
-
03
Ranked on reviews, not commission
Products are ordered by Amazon star rating and number of reviews, then filtered by whether they fit. Commission plays no part in the order.
-
04
You buy on Amazon, not here
Every button takes you straight to the product on Amazon. We never take a payment or hold your card details.
We earn commission from Amazon links. That doesn't change what you pay, what we list or the order it appears in. Read the affiliate disclosure.
