It's not unusual to hear stories of people buying infant tickets at the last minute and being shocked at the expensive fares that must be used for this, including cases when the adults have award tickets.
So it's safe for a kid 1year and 364 days old but unsafe for a kid 2 years and 1 day old? Wondering .....
