Frequently asked questions

Is it cheaper to buy a plane ticket from CPS to SNN last minute?
Booking your flight from CPS to Shannon Airport last minute could save you a pretty penny if you happen to find a bargain. However, airfares generally don't get cheaper closer to the departure date. If you take a wait-and-see approach, flights could also be booked out or the best seats gone (that could mean the middle seat!). If you'd rather play it safe, book well ahead of your departure date. Don't forget that some of the biggest bargains can be found up to 12 months in advance. If your favorite carrier hasn't released tickets yet, check back regularly as offers are updated on Expedia constantly.

From East St. Louis, you can travel to Shannon through Shannon Airport (SNN), Galway (GWY) and Kerry Airport (KIR). Do some research into which hub is the right option for you before making your decision. If you pick Shannon Airport (SNN), it's approximately 5 kilometers southeast of downtown.
