Boeing ( BA) says new-order financing is secure into mid-2010, but questionable afterwards.

"We're very cautious as we get to the midpoint of next year," said Scott Carson, CEO of Boeing Commercial Aircraft, at a JPMorgan investor conference Tuesday.

2010 "will be telling for all of us in the industry," Carson said. "We're watching each of our customers and where they stand on a daily and weekly basis."

As for the current year, "with financing commitments that have already been made, we believe every one of the airplanes scheduled for delivery will be delivered," he said.
