Excluding one-offs, Delta Air Lines has scheduled 864 routes in April: 684 domestic and 200 international. The SkyTeam member will fly to 297 airports globally. On a typical day, it’ll have 5,150 takeoffs and landings—more than any other carrier in the world except American.

Compared to last April, Delta’s offering has risen by 4%. Given the airline’s vast scale, that is a strong growth rate in relatively little time. However, it is only its ninth-best year for April activity. Yet, seats for sale have risen—they’re at their highest level to date—partly because of a greater use of higher-gauge aircraft. All this information is from examining Delta’s schedule submission to OAG.

Delta’s Top 10 Routes In April

Obviously, any focus on a specific period—day, week, month, quarter, year—necessarily reflects what is available at that specific time. It may easily vary at other times. This is absolutely the case for airline schedules, with the added bonus of other things, including equipment, changing too. As such, treat the following list as reflecting what’s available in April only. Unsurprisingly, none of the routes use the Boeing 717. And none of them have the carrier’s lowest seat factors.

One of the various things that jump out is the relative lack of flights on the 757-200. Indeed, except for Atlanta to Orlando and Tampa, the variant will barely be deployed. When all the following routes are combined, OAG shows that departures are down by 34% compared to April last year. This reflects the carrier’s networkwide reduction in the use of the equipment (-33%). This particularly relates to the 199-seat configuration (-37%). They’re being replaced by much more efficient aircraft, albeit with much higher ownership costs.

This route, which covers 351 nautical miles (650 km) each way, plays an important role in Delta’s network. Compared to a year ago, the carrier’s departures have risen by 6%—from 465 to 492. That’s equivalent to an extra daily service. However, due to lower-gauge aircraft, which have reduced seats per flight from 205 to 199, seats for sale have only grown by 2%.

Up to 17 daily departures are available this month. Let’s consider the randomly chosen April 9. Some 15 of the day’s 17 departures will be on the 757-200. Really bucking the trend, this figure is up from 11 flights on the equivalent day last year, when more twin-aisle services—on the A330-200, 767-300ER, 767-400ER—were available.

On Thursday, April 9, these Delta flights will leave Atlanta for Orlando: 7:15 am (757-200), 8:15 am (757-200), 8:45 am (A321ceo), 9:25 am (757-200), 10:25 am (757-200), 11:35 am (757-200), 12:40 pm (757-200), 1:45 pm (757-200), 2:50 pm (757-200), 3:55 pm (757-200), 5:05 pm (A330-900), 6:15 pm (757-200), 9:20 pm (757-200), 8:30 pm (757-200), 9:35 pm (757-200), 10:40 pm (757-200), 11:40 pm (757-200).

Delta’s Numbers Between Atlanta And Orlando

According to the US Department of Transportation, Delta carried 1.9 million round-trip passengers between Atlanta and Orlando in 2025. An estimated 580,000 passengers were local. They only flew between the two cities; they did not fly elsewhere. Delta had just over half of the huge point-to-point market (51%).

This means that just over 1.3 million passengers connected to another Delta flight in Atlanta. Relating this figure to booking data, which identify where passengers go, suggests that about 86% of passengers continued on another domestic flight.

At the airport level, the top 15 segments via Atlanta were Huntsville, Memphis, Las Vegas, Little Rock, Kansas City, Greenville/Spartanburg, Nashville, Pensacola (!), Cleveland, Charleston, Birmingham, Milwaukee, Indianapolis, Knoxville, and Jackson. The most popular international market was Rome, in 56th place.
