In which terminal will I find arriving Delta Flight No. 3506?

ONTario has 2 different terminals. In Terminal 2- you will find Delta, United Airlines, Alaska Airlines, JetBlue Airlines, China Airlines and Frontier. In Terminal 4- you will find Southwest Airlines, Hawaiian Airlines, and American Airlines. 😀

Terminal 2. I find looking online through the airline you're flying would give you all the info you need. Just know what city you're flying from and to. Or your flight#. Always get the best info.

Terminal 2

I used Southwest. Sorry.

I fly United Airlines but you can call customer service for Delta and get the specifics from them especially since you have a flight # Good luck

Delta uses terminal 2

Not sure since I used Frontier
