WASHINGTON, June 5 (Reuters) - Delta Air Lines ( DAL )

warned new tariffs on imported airplanes and parts could force

the airline to stop buying foreign-made planes impacting

millions of customers.

The Atlanta-based carrier told the U.S. Commerce Department

in comments seen by Reuters Thursday that in 2023 and 2024 it

took delivery of 47 Airbus aircraft produced in Canada,

Germany and France. If the carrier had not been able to take

delivery of those planes because of tariffs it would have forced

flight cancellations impacting 10 million customers. Delta said

a "similar impact could be expected going forward" if the Trump

administration imposes new tariffs.
