A maps app covers the drive to SNA. Bag drop, security, and the walk to your gate usually take longer, and they are the steps people misjudge.
Here is the same plan drawn to scale. The first block is travel; the next two are the airport. A checked bag grows one, a far gate grows the other.

Ninety minutes to two hours before departure covers most domestic flights out of SNA. Checking a bag or flying at a peak hour puts you toward the early end of the range.
John Wayne is one of the few airports that officially asks for less than two hours (ninety minutes to two, in its own words), and the reason is the size: one terminal, twenty gates, and a walk from the parking structures rather than a shuttle. The catch is parking. The structures next to the terminal fill, and when they do the overflow is a shuttle lot on Main Street, which turns a five-minute step into a twenty-minute one.
Terminals A, B and C are one connected building with a checkpoint for each, and the gates are close behind them, so the walk after security is the shortest step in the plan. The line itself is usually modest; the morning departure bank and holiday weekends are the exceptions. Which terminal you use follows your airline (American, Delta and Air Canada in A; Alaska and United in B; Southwest and Frontier in C), and it decides which structure to park in.
The plan allows 20 minutes for a standard lane on a busy but normal morning. With TSA PreCheck, that drops to 10 minutes. A checked bag lengthens the one before it.
The airport sits at the meeting of the 405, the 55 and the 73, which puts most of Orange County within a short drive and makes rush hour the whole risk. There is no rail: the nearest stations are ten miles away in Irvine, Santa Ana and Tustin. Rental pick-up and return is on level 0 of structures A2 and B2, an elevator ride below the terminal, so returning a car is a walk. Park early rather than circle; the structures post their status and fill on busy mornings.
For live waits, parking, and terminal maps, check the official SNA site.

Ninety minutes to two hours before departure covers most domestic flights out of SNA. Checking a bag or flying at a peak hour puts you toward the early end of the range. The plan above works back from there through security, bag drop, parking and the drive to a leave-by time.
The plan allows 20 minutes for a busy-but-normal standard lane. With TSA PreCheck it drops to 10 minutes, and you can edit either one to what you actually see. A checked bag lengthens the step before it. Checkpoint detail for SNA is under Security at SNA above.
Earlier than for a domestic one. International boarding starts 45 minutes before departure instead of 30, which pulls every step earlier. Use the airline desk for bags: documents get checked and counters often close an hour out. That also covers lap infants, unaccompanied minors, and oversized bags. If your boarding pass names a boarding time, match that.
Work backward from departure: boarding, time at the gate, the walk, security, bag drop, parking, then the drive (15 minutes in the default plan). Replace the drive with your own route. The leave-by moment is the first travel row, "Drive to SNA" by default.
Taking the train instead? The Amtrak station pages use the same kind of plan without security. Flying from somewhere not listed? The airport leave time calculator has the same rows with your own numbers, and the wake-up time calculator runs it back to the alarm.
Start the plan in the app, and the Lock Screen and Dynamic Island show the time left, with a bar that fills as each step passes.
Glance at it in the terminal without opening the app.
Every step also gets its own alert, and sharing the plan gives whoever is driving the same leave time, with alerts on their phone.
