The lovely people called travel agents
Now that I've reminded you of such advice, do remember that if you're a first-time solo traveller and you're talking to travel agents who live off the commission of getting you to pay for a trip, do try not to be bothered by some of their condescending tones of annoyance and impatience to get you off the phone if you ask a lot of "basic" questions and don't sound like you're fully ready to buy from them. Eventually, you will learn how to sound like you will, even if you don't readily mean to, that way they might sound a bit more helpful with your questions. If you're not in a rush and you have sufficient amount of time to plan ahead, call their office before making a personal visit- it will save you time, gas, and it won't give them an idea of how you look. Of course, jotting down questions and anything else that causes concern is a good idea. However, if you're like me, your quickly-written notes can sometimes resemble things worse than chicken scratch that by the time you need to quickly reference them, they've been completely translated into an alien language. Take the time to clarify them, and even if you look a bit rattled while talking to an annoyed agent in person, be sure to make yourself understand situations. Do not let their snotty looks of amusement from your conversational blunders get to you. If you do come across such, do not feel sorry for yourself but regret their lack of Christian charity and give them a smile and thanks, for those who lack such virtue really don't know what they're missing and an opportunity for you to be humilitated gives you twice as much glory.
Consider yourself blessed if you come across a very understanding agent that knows what it feels like to be a nervous "first-timer" and renders you the dignity you deserve when you have to deal with one of the most complicated and merciless industries known as the airlines.
With anything else in life, never forget how it feels to be a vulnerable newbie.
