Sky Harbor Airport officials say there are no specific terrorist threats in the aftermath of the Istanbul airport attack, but they remain at a high level of security.
Some people have called for airport checkpoints nationwide to be moved to terminal entrances to enhance safety after attacks overseas. A Sky Harbor spokeswoman emphasizes travelers are already subject to search anywhere on airport property.
On Wednesday, there was a strong presence of uniformed police officers and TSA agents in the unsecured parts of the terminals. An explosive sniffing dog was patrolling in Terminal 4, the busiest at the airport. Checkpoint lines appeared to have normal wait times.
Sky Harbor officials remind people traveling during the Fourth of July holiday weekend to arrive two hours early for domestic flights and three hours early for international flights.
