Changes from I1 to I1

For trips where the travel by train or bus takes more than 12 hours, a plane ticket will be reimbursed on the basis of an economy class ticket. A plane ticket can also be reimbursed if the destination was over 750 km or train-traveling is not possible because of pressing time-table reasons.

Direct flights as well as combinations of direct flights with ground transportation are to be preferred over multistop flights due to the increased emissions from multiple starts and landings. Due to the high levels of emissions, plane-travel in general should be avoided as much as possible.
