Delta Air Lines asked the United States Department of Transportation (DOT) for a temporary dormancy waiver to avoid operating part of its authorized frequencies between the United States, Cuba and mainland China during the IATA winter season, from October 25 to March 27, 2027. The measure would allow it to retain its traffic rights without losing the frequencies due to the 90-day non-use rule.
The request comes after the DOT itself granted a similar waiver in March for summer 2026 (March 29-October 24) and required the airline to resume use of those frequencies no later than October 25 this year. Delta argues that market conditions did not improve enough.
Delta holds 21 weekly frequencies to Cuba: 14 Miami-Havana and 7 Atlanta-Havana. It asks to suspend the 7 from Atlanta and 7 of the 14 from Miami, so that only a daily Miami-Havana flight would operate.
- What is Delta requesting from the U.S. Department of Transportation?
Delta is asking for a temporary dormancy waiver to avoid operating selected authorized frequencies to Cuba and mainland China during the IATA winter season (Oct 25, 2026–Mar 27, 2027) so it can retain traffic rights without losing frequencies under the 90-day non-use rule.
- Which Cuba routes does Delta propose to suspend?
Delta proposes suspending the seven Atlanta–Havana weekly frequencies and seven of the 14 Miami–Havana weekly frequencies, leaving one daily Miami–Havana flight.
- Which China frequencies would be affected?
Delta would suspend 23 of its 42 authorized weekly U.S.–China frequencies, including all Beijing service and reductions on Atlanta–Shanghai and Los Angeles–Shanghai, while maintaining Detroit–Shanghai, Seattle–Shanghai, and five weekly Los Angeles–Shanghai flights.
- Why is Delta seeking the waiver?
Delta cites weak demand, a poor economic outlook in Cuba, reduced international tourism, stricter rules for Cuban travelers, bilateral frequency limits with China, and uneven recovery in business and leisure demand.
- If the waiver is approved, will Delta lose the frequencies?
No. Approval would allow Delta to retain the traffic rights for those frequencies while suspending service temporarily; it could reactivate capacity if demand recovers. DOT evaluates extensions case by case.
The airline maintains that United States-Cuba demand cannot sustain those frequencies, citing an adverse economic outlook on the island, a drop in international tourism and stricter restrictions for Cuban travelers. The traffic that holds up is mainly visits to family and friends originating in South Florida.

This is not an isolated cut: other United States airlines (American, JetBlue, Southwest) have also requested or received waivers for Cuban routes. Canadian airlines suspended their services to the island indefinitely this year. Delta retains its rights and says it could reactivate capacity if demand recovers.
Mainland China: 23 of 42 frequencies on hold
Delta has 42 authorized weekly frequencies in Zone 1 United States-China: 28 to Shanghai from Atlanta, Detroit, Los Angeles and Seattle, and 14 to Beijing from Seattle and Detroit. It requests not to use 23 of them during winter 2026/2027.
According to the filing, the entire service to Beijing would be suspended, along with the 7 Atlanta-Shanghai frequencies and 2 of the 7 Los Angeles-Shanghai frequencies. The daily Detroit-Shanghai and Seattle-Shanghai flights would continue, in principle, plus five weekly Los Angeles-Shanghai (the airline had already announced an increase from 3 to 5 weekly on that route starting October 2026).
The market is constrained by bilateral agreements (around 50 weekly frequencies per side for United States and Chinese operators) and by an uneven recovery in business and leisure demand. Delta has requested similar waivers in previous winters and has made clear it could need further extensions.
If the DOT approves the motion, Delta does not lose the frequencies; it simply reserves them while adjusting capacity to actual demand. The DOT warned in previous decisions that each extension is evaluated case by case and that there is no guarantee of new concessions. United States regulatory restrictions on travel to Cuba remain in force; the waiver does not modify them.
The request is part of a broader adjustment to Delta’s winter 2026/2027 network, combining seasonal cuts, fleet changes and some expansions in other regions. For passengers, the immediate effect would be less direct Atlanta-Havana connectivity, fewer Miami-Havana seats and the absence of Beijing from Delta’s network during that winter, with Shanghai concentrated in Detroit, Seattle and, to a lesser extent, Los Angeles.
