American, Delta and United plan to add 15 long-haul international routes in September

American Airlines, Delta Air Lines and United Airlines will resume as many as 15 long-haul international routes in September, even as the return of flights during the coronavirus pandemic slows.

If schedules hold, Accra (ACC), Barcelona (BCN), Buenos Aires (EZE), Lagos (LOS), Mumbai (BOM) and Rome (FCO) are all due to see their first U.S. airline-operated flights since the pandemic began. However, as in months past, the plans remain subject to change until flights are actually in the air.

For example, American and United's flights to Hong Kong remain suspended due to local COVD-19 testing concerns. The Star Alliance carrier has postponed plans to add flights between Chicago O'Hare (ORD) and Hong Kong this month after a more than year-long hiatus.

Hawaiian Airlines' long-haul operation remains grounded until at least the end of September due to its namesake state's mandatory 14-day quarantine for arrivals. The carrier has warned more than 2,000 staff — about a quarter of its workforce — of possible furloughs due to the continued grounding.

International route resumptions are expected to slow as the U.S. moves into winter. The period is traditionally a time of lower travel demand in many long-haul markets, something that will likely be exacerbated by continuing border restrictions in many countries.

Below are the international long-haul routes planned by U.S. airlines for September as of Sept. 1. Bolded routes are due to be added or resumed in September.
