The 'Best time to book' tends to be a contentious issue amongst travelers but consensus typically finds that approximately 70 days before the departure constitutes the optimum window for capturing the most economical airfare deals. An earlier booking window, especially for the less frequented route towards Grand Island, may lead to cost savings. Furthermore, the benefits of 'flight deals' may include perks such as larger baggage allowance, extended frequent flyer benefits, and better flight schedule options.
