Let’s set aside the pros for now and find out if there’s even any cons to flying first class.

The main disadvantage of flying first class is that you’ll not want to disembark from the flight once you have reached your destination. You wouldn’t want to come out of the dreamy bubble you’re in.

Next is the cost that you have to pay for such a limitless luxury, a priceless experience. But once you have flown downbest first class to Houston, you’ll realize, that it’s worth every penny.

Then, comes in a disadvantage which has once in a trillion chance of happening. The first class is situated in front side of the aircraft & hence the part with the lowest survival chances in case of a fatal crash.J

The worst kind of disadvantage is that your friends will envy you.

In best first class to Ko Samui(or anywhere else),you get the best food, the best seats, the best service—even the best air quality, as air moves from front to rear of the plane.J

And you have lounge access, deplane first, collect baggage first, are fast-tracked through security and immigration, an extra bag checked for free, speedy boarding/security and more leg room.

Lounges:

First Class lounges are amazing. There’s buffet breakfast, lunch and dinner with all options. The waiters will run over and get it for you. In addition to the food, free internet, magazines, etc. there are private cabanas that are shower suites with a day bed in some lounges. In addition to departure lounges, some major hub cities (NY, Hong Kong, London, Frankfurt) have arrivals lounges.

Gate transfer:
If your gate is more than a certain distance from security (at Hong Kong Airport), they give you a ticket for a golf cart to take you out to the gate. If you have a tight connection they’ll meet you at your arrival and whisk you off to get to your connecting flight.

Private security lines:
Some airports have private security lines. At some places this just means a shorter line. At others this means a separate, more private screening area.

Freshly cooked food:

Tell them how you want your foodand they’ll make it that way. They’ll entertain a snack between meals too.
