I flew 15 hours in business class, and I don't think I could ever do a long flight in economy again

I was a bit worried about spending 15 hours flying, so I took the plunge and booked myself a business-class ticket for $2,600 on Swiss Air. For context, an economy ticket for the same one-way flight typically costs around $650.

My total flying time from New York City to Dubai, United Arab Emirates, was just over 15 hours with a brief layover in Zurich, Switzerland, to break up the time spent flying.

Here's what it was like flying business class on the long journey:

LaGuardia Airport was emptier than I thought it would be.

Even though I was missing some paperwork, I was able to check in at the Swiss Air desk, breeze through security, and head to the Swiss Lounge in about 30 minutes.

I scanned my ticket to enter and the attendants kept me posted when the flight began boarding.

Access to lounges like these was a fabulous perk of flying business class. They have comfy places to sit, food, chargers, and showers.

Business class was in the first group to board, and it was nice to head directly onto the flight without waiting in line or for my number to be called.

Upon boarding, flight attendants took my coat and hung it up. I also got sparkling wine.

There were either one or two seats by the window on the right, two seats in the middle of the aircraft, and one or two seats by the window on the left.

The flight attendant mentioned to us that the business class was around 15% to 20% capacity and relatively empty.

It made the service even better for those of us who opted to fly business class and gave us the ability to move to any seat we wanted.

The business-class seats each had a plush pillow and blanket to make the overnight flight as comfy as possible.

I left New York at around 9 p.m. and wanted to sleep on the plane so these items were key.

There was also a fancy Victorinox amenity kit at my seat. It included a toothbrush, toothpaste, a light-blocking eye mask, earplugs, and a pair of socks.

Since it would be morning when I landed in Zurich (and nighttime in New York), I wanted to get my body adjusted to the time in order to avoid jet lag.

My plan was to have dinner and then head to sleep.

I wasn't worried at all about where I'd put my carry-on and purse.

There was a compartment underneath the screen, one in front of me, one for my shoes, and plenty overhead.

You could also use it to track the flight or listen to music. I didn't use it much.

After take-off, I ordered dinner before I fell asleep.

I chose the salmon, which was delicious, and some vegetables. The quality of the meal was a pleasant surprise since plane food is typically not the greatest.

It didn't taste like it was packaged and the flight attendants made my tray into a gourmet table, complete with a tablecloth and silverware.

It had a huge mirror and plenty of space inside.

You could also put a cover over the toilet if you wanted to sit down and do your makeup or skin care. The bathroom was also super clean.

Thankfully, because the seat was controlled by me, there was no need to ask anyone to help me to move it. I was easily able to adjust the way it was positioned.

Overall, this was the best I've ever slept on a flight. I was slightly woken by some turbulence, but I slept for the bulk of the flight.

The makeshift bed was much more comfortable than I thought it would be. Plus I got extra pillows and blankets because the business class was so empty.

The seats also extended further than I was expecting. I'm only 5-foot-3, but my 6-foot-1 dad was also very comfortable in the lie-flat seats. He was able to comfortably stretch out his legs.

I have pretty severe allergies so I'm always playing it safe with food on flights.

The pastries I chose were all warm and quite filling. I was worried about getting jet lag, so I opted to go for smaller meals throughout the day to avoid getting sick.

I've flown for eight to 12 hours before, but those were direct flights.

Since I had a stopover in between, there was a sense of dread over having to repeat the flight experience a second time.

Being in business class certainly made the trek easier, but the flight is still extremely long. Sitting for this many hours was quite difficult.

It had a massive food buffet, showers, and plenty of places to lounge inside.

The lounge also had a gorgeous outdoor space. It was great for passing the time and it was close to the gates, which made it easy to quickly board when it was time.

The flight was set to depart around 1 p.m. in Zurich time and land at 10 p.m. in UAE time.

The plane was arranged the same as the similar flight in configuration and included lunch and snacks anytime aboard the flight.

The seat was also next to a window and came with a pillow, blanket, and Victorinox amenity kit (same as the previous flight but in a different case).

It also had an outlet port, reading light, and the ability to move into different lounging positions.

The seats looked nicer, but I had a little bit less legroom and fewer storage options than the first flight had.

I had almost double the space on the first flight. I still had a compartment for my shoes and a small place next to the seat for personal items.

I opted not to eat a meal on this flight and stuck to my own personal snacks since I had just eaten in the lounge.

The menu looked lovely, though, and included many Swiss-themed meals.

It had the same full-length mirror and lighting around it but had much less space overall. It felt about half the size of the bathroom on the previous flight.

There were old classics and some new, popular movies to choose from. In addition, I had the ability to watch the flight journey, listen to music, or watch TV shows.

To get comfortable, I pressed the lounge button, which stuck out the leg extension and slightly elevated the back. It was perfect for watching TV.

This flight went by quicker than I expected and I'm certain it had everything to do with being in business class.

Waiting in line at customs after a long flight is generally not fun, but this card made the process move quickly. It was a business-class feature that I never experienced or knew existed.

Little touches like this were definitely appreciated.

After this, I don't think I'll ever be able to do long-haul flights in economy again.

As someone who has a back injury, it made a huge difference in flying because I was more comfortable. Being able to stretch out and sleep also helped me avoid jet lag, which helped make my trip better overall.

At the end of the day, I'm glad I splurged on business class. It made the entire experience of flying 15 hours so much better than I could have imagined.
