B/c the air in the aircraft is quite dry, and at a lower pressure, so you're losing moisture when you breathe. It's good to drink water regularly to cover that loss.
because the persons want to drink plenty of water
That depends on the subject of the sentence. For example a first or second person subject, such as "I" or "you" would require "need." I need to drink plenty of water. Third person, with the exception of third person plural, uses "needs" John needs to drink plenty of water. Also, any time a group is referred to in the singular such as "this team" you use needs. However, if you were to say a proper name like "the cardinals" you would use need. In short it's: I/you/they/we need to drink plenty of water. John/he/she/ needs to drink plenty of water. "The basketball team" needs to drink plenty of water. "The Globetrotters" need to drink plenty of water.
