I would proceed with caution. Technically all flights to/from the US are covered but airlines are good at finding loopholes.
All airlines operating to, from, and within the U.S. must comply with the 24-hour rule.
The only exemption are flights purchases less than 7 days before departure.
The airline can meet the rule either by allowing cancellation within 24 hours OR by allowing to hold a are for free for 24 hours. They do NOT have to do both.
There are also potential loopholes with code shares and buying tickets not directly with the airline (Expedia, Priceline, etc.). As far as I can tell Kuwait air is currently running at least one flight to the US (JFK) so they can't use the excuse of "not operating in the US".
Good practice is to check their website and terms and conditions
According to the DOT, airlines have to be upfront with customers about the one-day refund grace period both on their websites and when they are contacted by passengers. This means that not only does an explanation of the 24-hour reservation requirements need to be visible in the refund policy sections of an airlineβs website (like on any terms and conditions pages or booking pop-up windows), but customer service representatives must also explain the rule to passengers who call them with questions about canceling.
If you can't find anything on their website or their contract of carriage, than chances are they think they have a viable loophole. Of course, you can always pick up the phone and ask directly.
In case they refuse a refund your only option is to file a complaint with the DOT. If this will ever result in them taking action, an actual refund and how long that may take, is anyone's guess. I personally wouldn't rely on that.
