No. Down to the last wire is no idiom I am aware of. It sounds like a mixed idiom. Down to the last man means you'll fight until all means of fighting have been lost. Down to the wire means the outcome won't be known until the last moment or things are going to be close at the finish line.
It simply means until the last possible moment.
The idiom down to the wire means to the very last possible moment. Therefore, the entire phrase would stand to mean that "it went to the very last split second and we almost missed your flight, but made it."
"Under the wire" means shortly before the deadline, e.g., "I caught the train just under the wire," or "I reached the destination of the interview just under the wire." It means "barely" or "scarcely."
