Incredible as it sounds, the recent increases to fares for the London Underground has made it cheaper per mile for passengers to fly first class than to take the subway.

According to the Travel Daily News, first class air travel is now 30 times cheaper per mile than the underground.

"The price of a single zone one journey, which can often be less than a mile in distance, has gone up to an astronomical £4 (US$7.77) and that is for a hot, crowded and often very uncomfortable journey.

Compare this with travelling first class on one of the world`s best airlines down under to Sydney and you have an average cost per mile of just 13 pence (about 25 cents US). Travel in economy and this brings the cost per mile to just three pence (6 cents US).

Imagine the difference in experience. One you're reclined in your seat, watching your favourite movie whilst drinking Dom Perignon and having a personal chef bring you whatever you desire to eat. On the other you're stuck between stations on a tube that is close to 100 degrees in temperature, jammed in like sardines with your head close to someone's smelly armpit."
