Leaving on a Tuesday is a viable option for saving on travel. Heavily demanded days of the week can typically drive up the prices you see. Booking your travel for a less competitive day can save up to 20% on the overall cost on flights from Chicago-O'Hare Intl to Frankfurt.
Travelers have found it’s best to book a flight 29 days in advance to save up to 12% 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 29 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 Chicago-O'Hare Intl to Frankfurt 1-2 weeks in advance for as low as $798, or $862 for flights within the next 24 hours.
