The average round-trip flight from Hartsfield‑Jackson Atlanta International Airport (ATL) to Milwaukee Mitchell International Airport (MKE) costs about US $295.
Key Elements Impacting the Cost
- Booking in Advance: Flights are typically cheaper when booked several weeks or even months ahead of your departure date. Last-minute bookings often incur higher costs.
- Time of Year: Peak travel seasons, such as summer holidays, Thanksgiving, Christmas, and spring break, see increased demand and consequently higher prices. Conversely, off-peak seasons like late fall (excluding holidays) or early winter often offer better deals.
- Day of the Week: Flying on weekdays (Tuesday, Wednesday, Thursday) is often cheaper than flying on weekends (Friday, Saturday, Sunday) or Monday mornings.
- Flexibility: Being flexible with your travel dates can unlock significant savings. Even shifting your departure or return by a day or two can impact the fare.
- Airline Choice: Different airlines offer varying price points and service levels. Budget carriers might offer lower base fares, while full-service airlines may include amenities like checked baggage or in-flight meals.
- Fare Class: Basic Economy fares are usually the cheapest but come with restrictions (e.g., no seat selection, no changes). Standard Economy or flexible fares offer more perks but at a higher price.
