Frequently asked questions

Is it cheaper to buy a plane ticket from STL to Cardiff Intl. Airport (CWL) last minute?
Booking your flight from STL to Cardiff Airport at the last minute could save you a nice sum if you're lucky enough to find a real steal. However, tickets generally don't get cheaper as the departure date nears. If you wait, flights could also be booked solid or the best seats gone (that could mean the middle seat!). If you want to be on the safe side, book well in advance of the date you want to leave. Note that some of the biggest deals can be found up to a year in advance. If your favorite airline hasn't released its fares yet, check back regularly as offers are updated on Expedia all the time.
What airports do you fly into for Cardiff from St. Louis?
Cardiff Intl. Airport (CWL), Bristol Intl. Airport (BRS) and Exeter Intl. Airport (EXT) are your choices when jetting from St. Louis to Cardiff. Around 14 kilometers southwest of downtown Cardiff, Cardiff Intl. Airport (CWL) is the city's main entry point. Take into account things such as flight arrival and departure times and the distance to your hotel before deciding where you fly into. Principality Stadium and Cardiff Castle are a couple of terrific attractions to explore when you arrive.
Can I change the date of my flight from Lambert Field to CWL?
You can make changes to your STL to CWL flight via the Expedia Trips portal. But before amending dates or times, read over the rules in your itinerary to see what you're able to do and what charges may apply. Some airlines have a change fee per person, on top of any difference in fares. But if you booked in the last 24 hours, you may be able to cancel for free and arrange new flights. You can also take a look at our Customer Service portal for more info and to connect with our Virtual Agent.
