This latest offering is available for free to SkyMiles members on many flights and supports high-speed browsing.
In this blog, we’ll explain “How Delta Airlines Wi-Fi works.” How much does it cost? Where is it available, and how to use it during the trip? So, stay connected and read on to know everything about using Wi-Fi with Delta Airlines.
Does Delta Have Wi-Fi Service?
Yes, Delta Airlines has Wi‑Fi on most of its flights. It allows passengers to use the net and is available on domestic and international routes. However, it may not be accessible on every plane as it depends on the type of aircraft and where passenger is flying.
What Is Delta Sync Wi-Fi?
Delta has introduced a service called Delta Sync Wi-Fi. This is a new type of in-flight internet that is fast and free for many travelers. It is powered by T-Mobile, one of the largest mobile networks in the U.S.
Delta Sync Wi-Fi is different from older systems. It allows to do more things online, like watch videos, scroll social media, and chat just like you would on the ground.
