SBD · Inland Empire gateway with **Breeze Airways** nonstops to **SFO** and **Provo (PVU)** — **no Priority Pass lounge** verified on research day; official on-airport parking marketed at **$5/day**; major cargo/Amazon Air hub with thin passenger F&B vs ONT/LAX.
ONT · Two compact 1998 halls with a real Priority Pass Aspire on each side and a $2 Metrolink shuttle — undercut by no airside T2↔T4 walk and a 35-mile slog to downtown Los Angeles.

T2 evenings and T4 mornings are the long lines
Official OIAA peak windows are Terminal 2 04:00–07:00 and 19:00–23:00, and Terminal 4 05:00–09:00. TSA says under 20 minutes off-peak and 30+ when a bank hits.
Pick T2 or T4 before you clear TSA
There is no post-security walk between Terminal 2 and Terminal 4. A covered landside walkway links them; changing terminals means reclearing.
Chick-fil-A is in both halls — closed Sunday
Official dining lists Chick-fil-A at Terminal 2 Gate 206 (opened Jun 2026) and Terminal 4 Gate 405, plus Brewery X in both terminals.
