Travelers have found it’s best to book a flight 50 days in advance to save up to 10% compared to booking the same week of travel. As your travel date approaches, the cost of this flight route may potentially increase. While opting to book 50 days out may not be an option for all, there are still additional ways to secure a deal in the near future. You might find a flight from Montana to Greece 1-2 weeks in advance for as low as $1081, or $1249 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in July. For low rates, February can be a great choice for travel to Greece. Flights to Greece from Montana in February are about $1023 on average during February, but can be found for as low as $402.
