American Airlines says it will discontinue flying to the Dallas-Fort Worth area from Oakland in September. It now offers three flights, daily.
The company says rising fuel prices are forcing it to drop service all around the country.
But the decision hits Oakland particularly hard, because it's lost three other air carriers in the past two months, in large part, because of skyrocketing fuel costs.
"Losing American is really tough for us. This is an airline that's been around for a very long time, as we know they have served Oakland for more than sixty years. It's such a disappointment to us. they've been such a wonderful partner," said Rosemary Barnes from Oakland International Airport.
Aloha, ATA and Skybus also stopped serving Oakland over the past couple of months, citing rising fuel costs and a decline in demand when they all declared bankruptcy.
