It's amazing to think that for many people, flying first class is as normal as brushing their teeth or drinking coffee every day. They don't think twice about spending thousands on plane tickets and they look forward to the luxurious experience.

The rest of us can't exactly pay that kind of money when we travel, so we look longingly at the first-class flyers when we're lining up to board the plane. And we totally feel like the grass is greener on the other side. But is that really true? Is first class the wonderful experience that it seems to be?

Here are 10 reasons that flying first class is not worth it, along with five reasons that you'll want to upgrade.

15 Not Worth It: Unless You're Really Tall, You Don't Need The Extra Space

As someone shared on Reddit, "First class domestic is nice, if you're a tall person, but for your average not-rich, average-sized person, not really worth it for flights less than 4 hours."

People who love first-class love the extra space, but if you're not super tall, then you wouldn't really find it necessary.

14 Not Worth It: The Cost Is Tough To Justify

The truth is that flying first class is really expensive, and for the majority of people, it's going to be difficult to find that kind of money. Can you really find thousands for a single plane ticket?

As a Reddit user put it perfectly, "However, it is still just a seat on a plane going to the exact same place at the exact same time."

13 Want To Upgrade: If You Have A Super Long Trip Ahead Of You

There is a time when first-class is totally worth it, though, and that's when you're going on a very long trip. Someone shared on Reddit, "Long haul flights... yeah it's worth it. Laying flat and getting a solid 7 hours of sleep? AMAZING!"

12 Not Worth It: Being Able To Board First Is No Big Deal

Express.co.uk mentions that priority boarding is something that first-class flyers really enjoy. But that doesn't seem worth it because being able to get on the plane early means more time sitting on the plane.

Everyone feels really stiff and tired after spending hours sitting in a plane seat anyway, right?

11 Not Worth It: You Can Live Without A Bigger Seat

One of the main bonuses of flying first class is having a seat that is bigger than the seats in economy. But is that really so exciting?

According to this Reddit post, "First class on most US domestic flights is just a slightly wider seat with free food."

10 Not Worth It: Some Extras Aren't Necessary

According to Business Insider, when you fly first class, you sometimes get into areas of the airport that are much fancier. You can use the shower or get a pedicure.

Those extras don't seem necessary, especially when you're spending thousands on a plane ticket. You can take a shower at your hotel or when you get home, and you can definitely get a pedicure another time.

9 Want To Upgrade: Fancy Headphones And Good Movies Could Help Nervous Flyers

According to this Reddit post, you'll find it easier to pass the time on a first-class flight: "Entertainment system is nice. Noise cancelling headsets are passed out... Hours melt by."

This could be helpful if you're not a great flyer and you get a bit nervous, and having those fancy headphones could help you relax.

8 Not Worth It: You Can Bring Food And Snacks

Sure, it sounds exciting to fly first class and be served a five-course meal and get unlimited snacks. Many people really enjoy this aspect of the travel experience.

But the truth is that while that's awesome, you can also bring your own food and snacks onto the plane.

7 Not Worth It: You're Given Proper Cutlery

According to Travel and Leisure, when you fly first class, you're given proper, legitimate cutlery. You also get nicer napkins.

This doesn't seem that worth it, though. Is it so bad to be served a meal without fancy forks and knives? Is that really what you're looking for when you're flying?

6 Want To Upgrade: You Feel Removed From Strangers

One of the worst parts of flying is that you feel cramped sitting next to people that you don't even know.

Flying first class is worth it only when you get your own area. Travel and Leisure quoted someone who said that the "seat is like a little pod - your divider is up and you cannot see who is next to you."

5 Not Worth It: You Could Definitely Spring For Premium Economy Instead

Thanks to a Reddit user, there's this really good tip.

They wrote, "Premium Economy is usually a pretty good, lower priced, product" and they mentioned that there's more space so if you want to take a nap on the flight, this is a smart idea.

4 Not Worth It: The Lounge Might Not Be That Amazing

People who fly first class always talk about getting into an airport lounge that has a lot of free food. But as One Mile At A Time says, sometimes it's not all that it's cracked up to be. The food could be "lukewarm."

3 Want To Upgrade: It's The Only Way To Be Productive

According to Inc.com, it's difficult to be productive when you're flying in the regular part of the plane. If you want to make the most of your travel time, you're traveling for work, or you're on a tight deadline and literally have to work on the plane, then it could be worth it.

2 Not Worth It: You Might Not Have Enough Points And Don't Fly Enough

Many people upgrade to first-class because they fly all the time and have a lot of points as a result. That makes a lot of sense.

But if you don't travel a lot, or you don't have enough points, it might not be quite so easy for you to upgrade. And you probably don't want to shell out hundreds or thousands more.

1 Want To Upgrade: It's A Calmer Experience

A Reddit user was able to fly first class as a child because their stepfather was employed by an airline, and they shared that there was always "Peace & Quiet."

If you've had bad luck with air travel in the past and you really want a better experience, then you might want to upgrade.
