Few things are more convenient than staying connected while you're in the sky. And Delta Air Lines has been hard at work improving the onboard experience over the past year and a half to reflect that.
In January 2023, Delta announced bold plans to introduce free Wi-Fi for SkyMiles members across its entire global fleet by the end of 2024. However, operational delays indicate the project shouldn't finish until sometime in spring 2026. But the airline is in the home stretch.
Over 1,000 aircraft — or more than 75% — of Delta's entire mainline and subsidiary fleets are now equipped with Delta Sync. And all that's left to go are some regional jets and a couple of Airbus A350-900 aircraft.
Here's what travelers need to know about the status of the expansive free Delta Wi-Fi rollout.
Most Mainline Delta Jets Are Now Wi-Fi Equipped
After months of retrofitting, Delta noted on December 8, 2025, that more than 1,000 aircraft are equipped with the new Delta Sync Wi-Fi product. That's over 75% of Delta's entire fleet. And the project should be completed sometime in 2026.
Which Delta aircraft have free Wi-Fi
Currently, Delta's website indicates that fast, free Wi-Fi is only available on its domestic mainline jets. Namely, the following aircraft should have free Wi-Fi by now:
- Airbus A220-100
- Airbus A220-300
- Airbus A319
- Airbus A320
- Airbus A321ceo
- Airbus A321neo
- Airbus A330-200
- Airbus A330-300
- Airbus A330-900neo
- Boeing 737-800
- Boeing 737-900
- Boeing 757-200
- Boeing 757-300
- Boeing 767-300
- Boeing 767-400
The Airbus A350-900 and CRJ-700/900 are the next aircraft types Delta will add to the list. At the time of writing, Delta isn’t finished retrofitting these fleets, so some aircraft will offer free Wi-Fi, while others will still require you to pay for it.
Delta aircraft with paid Wi-Fi
The remainder of Delta's fleet — mostly regional jets — have paid Wi-Fi options provided by ViaSat or Wi-Fi Onboard. Here are the Delta aircraft types with paid Wi-Fi:
- Boeing 717
- Embraer ERJ170/175
As mentioned above, you might still find an A350-900, CRJ-700, or CRJ-900 out in the wild that only offers paid W-Fi. But these are becoming more of a rarity as Delta wraps up its retrofits.
Delta Wi-Fi coverage map and limitations
Even though it's completely free (on most planes), Delta's Wi-Fi coverage worldwide is somewhat limited. Per Delta's coverage map, flights transiting certain regions won't feature coverage at all, even if the flight is operated by a Wi-Fi-equipped plane.
By region, coverage looks like this:
- United States (contiguous 48 States): Full Wi-Fi coverage
- Hawaii: Full Wi-Fi coverage
- Alaska: Limited Wi-Fi coverage
- Canada & Mexico: Full Wi-Fi coverage
- Europe: Full Wi-Fi coverage
- South America: Majority Wi-Fi coverage
- Asia: No Wi-Fi coverage
- Africa: Majority Wi-Fi coverage
How to Tell if You'll Get Free Wi-Fi on Your Delta Flight
The above assumptions won't assure whether your next flight will have Delta free Wi-Fi. But Delta's website will. You'll see it on a banner above select itineraries like this:
Assuming the Wi-Fi works on your aircraft as expected, you should have Delta free Wi-Fi on your flight if you see the banner above your itinerary.
Delta International and Regional Aircraft Wi-Fi Rollout Timeline
If most of your Delta flying is on aircraft the airline hasn’t finished retrofitting yet, rest assured that Delta plans to complete free Wi-Fi installation by sometime in 2026 — hopefully early in the year.
Delta officially kicked off the project in 2023, and what remains is largely the regional fleet, including subsidiary Embraer 170 and 175 and CRJ-700 and -900 aircraft, along with mainline Boeing 717s.
For all intents and purposes, Delta is nearly finished retrofitting its A350 fleet, which is a big win if you do a lot of long-haul flying on these jets.
Like many developments in travel, the original goal of completing free Wi-Fi by the end of 2025 may have been a bit on the too-ambitious side. Delta is in the home stretch, though, and we should be able to report that the rollout is complete sometime in early 2026.
Final Thoughts
Delta is investing plenty of resources into upgrading its onboard experience, and introducing a top-notch Wi-Fi experience across its global fleet by the end of 2025 early 2026 is part of that endeavor.
If you're a Delta SkyMiles member who loves to stay connected while flying, you'll appreciate the extra savings and functionality of having fast, free Wi-Fi at your fingertips. It's only a matter of time until Delta free Wi-Fi is available on every jet.
