If you are price conscious, and only need a flight for the day, United's basic economy is for you. However, for the price of one bag added to your flight, you will find a plethora of airlines that include carry-on, snacks, and beverages. Be cognizant of the low cost as a bait and switch to get you to purchase the ticket. Once you have purchased, you cannot change anything associated with your ticket. Everything is an added cost - buyer beware!
