What age range does the INF / INFT code apply to?

The INF / INFT code is specifically designated for infants traveling on Ryanair flights. This code applies to passengers aged from 8 days up to 23 months. This age range is crucial for airlines to appropriately manage services tailored for very young travelers, such as additional safety measures, seating arrangements, and provisions for infants. Infants in this range are typically still considered lap children and are eligible for certain services that are different from those provided to older children or adults. Therefore, recognizing that the correct answer encompasses this specific age range helps clarify the intended understanding of the INF / INFT code in the context of airline protocols and passenger classifications.
