I am a mostly leisure traveller,
although I travel for business two or three times a year.
For leisure, it is maybe 10 return flights (at least
one intercontinental from Europe).

There are several "is it worth it" topics on business
vs. economy class that I don't understand. I like to travel
light, so extra baggage allowance is not a feature I ever
used and for short-term flights I try not to check in
baggage (less waiting time).

My American Express Gold also includes Priority Pass
membership, which allows me lounge access almost anywhere
with any ticket, even with budget airlines.

I don't know if pure business class ticket gets me to better
lounges, but I am okay with these: I can relax, read,
browse internet, usually get a shower and have a drink or
light snack. And it looks as much better deal (even if I
had to pay for it) than sticking with one airline alliance,
which would get me to their lounges on their flights only.

So, if I understand it correctly, business class gets
me: better food, more leg room, less waiting (with online
checkins, there is rarely any waiting at all at the
checkin counters and I don't need to board my plane
first, as it flies together with all passengers) and
more ticket flexibility (rebooking) and more miles.

Is it worth it? I know there are people that get high
just from the "status feeling", but I like to spend
my money well. Is the business class price worth the money?
If it is $1000 more for 8 hour flight, isn't it better to
invest those $1000 in a better hotel and a good restaurant
while on ground and sleep during those 8 hours on the plane?

(note: I understand the ups and downs of budget airlines
vs. classical ones and of frequent flyer topics and that I
should always try to get the best deal, which includes
considering miles earned).
