So many things make air travel stressful during the holidays. The anticipation of spending time with relatives, messy weather and possible delays, and, of course the crowds -- it's enough to make even the jolliest of elves fret. 

To make matters worse for the less-than-tolerant, more kids of all ages are flying to grandmother's house this time of year. But before your inner Scrooge starts to surface as you watch kiddos board your flight, consider what their poor parents have to deal with. 

Travel writer Erica Silverstein wrote about this in her "Open Letter to People Who Hate Flying With Kids." She told Take Two that holiday flyers should keep in mind, "[Parents] are probably more worried than you are about their kids being problems, so they will have come prepared . . . with everything they can think of to keep their kids quiet on the plane."
