I do an advanced search for flights, using multiple airports and flexible travel dates.I'd like to know where you get such deals because I've found Business class to be triple the fare, often $4000 or more on international flights. For about $200 in perks.
Most often I can find a domestic business class seat at a good price from one airport that's not much more expensive than an economy ticket from a different airport, if you factor in the baggage fees for economy and the "extra leg room" upgrades.
Too many people seem to focus on the dollar value of perks, but they neglect the intangible advantages. Like the refreshment of getting a shower and changing clothes on a layover after a 19 hour flight before another 7 hours of travel. Like arriving at the destination fresh and rested. Like sitting in a quiet lounge in a big comfortable chair, away from the noise and crowds, with all the food and refreshments you want at your finger tips. Like sitting for 19 hours in a seat twice as big as an economy seat in your own private pod, with the option to lay back flat whenever you want.
I've made many trips halfway around the world, both in economy and business class. The difference in the experiences is something you should try.
