Passengers have a 83% chance of getting in-flight Wi-Fi when flying on US airlines according to the latest Routehappy industry report.
That is up from about 74% in 2015.
However Routehappy, which assesses onboard airline amenities, said that percentage dropped to just 28% globally.
There is now 70 airlines worldwide offering in-flight connectivity.
United Airlines was one of the top carriers, along with Emirates and Lufthansa for the availability of Wi-Fi on long haul international routes.
While in-flight Wi-Fi is being rolled out at a rapid pace in the US and beyond, Internet speeds are still frustratingly slow.
Just 7.2% of planes worldwide offer Wi-Fi speeds capable of streaming movies, it said.
That is up slightly from 6% from a year ago.
Routehappy says JetBlue and some planes in the United Airlines fleet offer the best Wi-Fi speeds.
JetBlue last week announced it has rolled on Wi-Fi across its entire fleet
