Bonjour,
a. Take the UNION STATION FLYAWAY BUS that will pull up in front of your terminal every 30 minutes. The bus will pull up under the GREEN OVERHEAD SIGNS that say "Flyaway Buses and Long Distance Vans". ($3 fare, 30-45 minute ride)b. Transfer to the Union Rail Station (adjacent to the bus depot) and take the next amtrak (amtrak.com) or metrolink (metrolinktrains.com) train to Santa Ana. ($12 fare, 50 minute ride)
Traduction vite faite: Pour 3$ le bus-navette jusqu'à Union Station et de là le train Amtrak ou le metrolink.
De la gare d'Irvine à votre destination finale.... le taxi.
