Airbnb has for the last few years been to place where groups of friends go to book accommodation. Bigger properties allow groups stay together and often pay significantly less than booking a series of hotel rooms when traveling.
As of today they have added a feature which will make this whole process much easier as you can now split the cost between up to 16 different people. This is great as previously one person would need to cover the whole charge and then get it back from each member of the group.
One thing also worth remembering with Airbnb is that you can collect Delta miles for every dollar spent. It’s easy to link your SkyMiles number to you account and go from there. Of course this may mean you want to pay the whole lot and get the miles however at least now you have a choice.
