Good to know
- Compare both airports when you look at fares, and keep weather in mind if you travel in late summer.
- Weekend flights are often busier, so a midweek departure can change the price picture. Ask about event dates before you lock in travel.
- Compare the total with bags included, not just the base fare. See baggage fees and taxes and fees.
