Avoid the bulkhead seats.
Remember this rule: if there are passengers with babies onboard, they’ll most likely take the bulkhead seats. This is simply because it’s easier and safer to place a baby carrier there. So if you love cute screaming neighbors, you know which seat to choose.
Drink only bottled water.
The problem of filthy water onboard aircrafts has gained a lot of attention since the scandalous study of the Wall Street Journal in 2002: the number of bacteria in water samples from 14 of the most popular airlines was hundreds of times higher than the established standard. Today’s situation hasn’t changed a lot, so it’s better to drink only bottled liquid onboard. Tea, coffee, and water from the sink should be avoided.
