Delta Air Lines will soon offer fast and free Wi-Fi on all of its flights after announcing its plans to do so in early 2023. As of mid-2025, more than 900 aircraft are equipped with internet. That includes all Boeing 737 and 757 planes and Airbus A321ceo, A321neo, A319, A320, A221 and A223 planes.
The rollout is continuing on the airline’s more than 400 regional jets and Boeing 717 planes. It's expected to be completed in early 2026. Transatlantic planes also have streaming-quality Wi-Fi, and soon flights to South Africa and transpacific flights will have it.
The Wi-Fi streaming product is called Delta Sync, which offers personalization for passengers using their SkyMiles frequent flyer numbers. It also connects the seatback entertainment devices to a personal account, providing a customized service Delta says makes “your seat in the sky feel more like a seat in your living room.”
Just because the plane has Wi-Fi does not mean you will have service during your entire flight. Full coverage is available in the contiguous 48 states, Hawaii, some of Alaska, all of Canada, Mexico, Europe, Central America and the Caribbean. It is also available in some of South America and Africa, but not in Asia or Australia.
Internet providers Viasat and Hughes currently provide the service, replacing Intelsat systems (which was once called Gogo).
To find out if your flight has the streaming-quality Wi-Fi, look for a decal near the boarding door or the note “fast-streaming Wi-Fi” when searching for flights to book.

If the free, streaming Wi-Fi isn’t available, it will not show up.
How to connect to Delta Wi-Fi
If your flight has fast and free Wi-Fi, you should be able to connect as soon as the boarding door closes.
To connect:
With your phone in airplane mode, turn the Wi-Fi on.
Select “DeltaWiFi.com” from the available wireless networks on your device.
Your device should prompt you to sign in to the network. You do this by entering your SkyMiles number and password.
If you don’t get a prompt, open your browser and go to “deltawifi.com” and sign in from there.
In order to be fully connected, you might need to wait for a video from T-Mobile to play. Once it finishes, the screen should say you’re connected.
Select the network.
Log in using your SkyMiles information.
Make sure you watch the short video or you won’t be connected.
You can connect to the internet on multiple devices during your flight so you can use your laptop and message on your phone at the same time.
If your flight does not offer the full Wi-Fi yet, you can still get limited access to messaging capability for free.
If you have trouble connecting, there should be information about how to connect in the seat-back pocket.
Once connected, you can stream audio or video, but you cannot make voice or video calls. Please be considerate to your fellow passengers and always use headphones when watching or listening to anything.
How much does Delta Wi-Fi cost?
For flights that have the “fast, free Wi-Fi,” it is free for SkyMiles members. All you have to do is log into the network with your SkyMiles number and password.
If you aren’t a SkyMiles member, you can join for free either before your flight or onboard. Once you join, you will have access to the free Wi-Fi.
If you don’t want to join SkyMiles, you can pay for Wi-Fi access. It’s $5 per flight.
If you have an old Wi-Fi Onboard All-Day or Delta Global Day Pass, they’re no longer accepted.
For flights that still have “Wi-Fi Onboard” but not the fast, free Wi-Fi, you can still get free messaging, but you have to pay for full Wi-Fi. Those flights are flown on regional jets and the Boeing 717 aircraft. Select routes may also not have fast, free Wi-Fi available yet. The pricing for “Wi-Fi Onboard” is set by Intelsat rather than Delta, and ranges from $10 to $40, depending on the route.
T-Mobile customers get free Wi-Fi on the planes that still have the Intelstat (formerly Gogo) internet
