Business travel has joined the sharing economy - by necessity and plain old convenience.Flights are getting cheaper and even as we increasingly don't need to fly at all, when we do, there are endless options for travel, accommodation and office space within the sharing economy. And some of those options aren't new.First - do you fly at all? While flights are cheaper than ever, it is increasingly easy to meet from your computer. Maybe Skype or one of its VoIP competitors will do it for you instead? VoIP services are relatively cheap and often free, even for group calls. But when you do fly somewhere, you can of course always offset your carbon and salve your conscience. When you arrive at your destination, there are so many choices - book a car to pick you up through Uber; book your meeting room and workspace through LiquidSpace and then catch a train or pick up a car from GoGet or Hertz24/7 to get across town for the next meeting.If you are staying over night and looking for something different to the tired old hotel you normally use, book your accommodation on Airbnb.com and stay in a genuine home! There are limitless options. If you are a big time corporate traveler in a hurry, this might all seem a bit like hard work, but once you are organised, it's a smarter, more flexible way to get around and all you need is your smart phone and five minutes to book pretty much anything.
