Delta brings upgraded E175 jets to Aspen

Delta switched its Aspen service to upgraded Embraer E175 aircraft in November 2025, replacing the older CRJ700. SkyWest operates the flights for Delta Connection, with Atlanta and Los Angeles serving as the gateways. The change adds six passengers per trip while addressing performance limits that previously made the larger regional jet impractical at Aspen.

The airport stands 7,820 feet above sea level and has an 8,006-foot runway surrounded by mountainous terrain. Heat and altitude reduce engine output, and the E175 formerly could lose ten to 15 seats on warm afternoon departures to satisfy federal climb requirements. Its 93-foot 11-inch wingspan also sits narrowly below Aspen’s 95-foot airfield limit.

Embraer, General Electric and SkyWest solved the performance issue through software rather than structural changes. Revised engine controls provide 1% to 3% extra takeoff thrust at maximum power. Updated speed and flap settings also help the jet meet terrain-clearance standards with a full cabin. SkyWest is assembling a dedicated group of new and retrofitted Aspen-ready aircraft, with 25 planned by the end of 2026. Those jets can also serve ordinary regional flights because the added output is reserved for full-power operations.
