Thousands of people rely on these electronic signs daily to catch their flights and reunite with their luggage. Manual systems with lettering strips and numerals are still in use in many airports.

After a bid is prepared and bid bonds are secure, there's a public bid opening. At this stage, it's still doubtful that a local sign company will win the contract. The lowest was a general contractor.
