Anyone can attest to the fact that flying in economy on an ultra-long-haul flight is not exactly the most comfortable. Passengers and airlines alike have attempted to make the least premium and cheapest cabin experience as enjoyable as possible, but having a larger seat, or in some cases, a suite, is arguably superior. However, premium seats come at a premium cost, which can be the deciding factor for some travelers. Nonetheless, some airlines have introduced premium-heavy cabins, while others have completely eradicated economy to feature an all-buisness class cabin on their longest flights.
