INS TE is a virtual marketplace where travelling commodities (such as airplane tickets) are traded. The inherent efficiency of marketplaces will bring about better as well as more transparent pricing of traded commodities and extremely low operation costs. INS TE will simplify considerably pricing mechanisms and reduce further intermediaries fees sustained by travel suppliers. INS TE will also greatly benefit the travel consumer by opening a whole new set of option (such as exchanging and/or reselling previously purchased tickets) that will render travelling commodities extremely flexible.
