If you’ve been calling Tampa International Airport “TIA” for short, you’ve been saying it wrong. Tampa International Airport sent a tweet out yesterday letting people know it’s “TPA” not “TIA.”
Locals have been referring to the airport as both “TIA” and “TPA” for what seems like forever now though, so don’t be surprised if they continue to do so. Just know that the correct abbreviation is “TPA” according to the airport itself.
