Business travel is one of the most stable working and highly profitable part of world tourism, and one of the youngest, too. Business travel or MICE (abbreviation from Meetings / Incentive / Conferences / Exhibitions) became a separate branch of tourism business in 1970s. First, business travel was considered by businessmen only as opportunities to have a good rest at the expense of the government or the company you work for. The situation changed greatly after 1998 when the number of entertaining trips has lowered and at the same time the number of corporate events has grown. MICE development in Russia is highly dynamic as well as in the rest of the world, and according to the prospects the profitability of this branch of tourism will grow up to $2 billion a year by 2020.

The demand structure of MICE today is: 75 % is individual business travel, intensive trips, conferences and exhibitions are 10—13 % each. The figures are approximate, of course; exhibitions and conferences are usually combined together in one event, and intensive programs usually supplement other types of business travel.

Meetings

Most travel agencies offer businessmen going to a conference, exhibition or negotiations only standard package of visa support, air tickets, accommodation and transfers. As a result those businessmen, who want their trips to be efficient, prefer dealing with specialized travel agencies working in the sphere of MICE tourism. Such travel agencies basically deal with corporate clients. Agencies can provide the corporate client with full package of business and travel services including dozens of meetings, visits to enterprises and professional exhibitions.

The biggest American travel agencies working in the sphere of MICE tourism are American Express Travel Services, Carlson Wagonlit Travel, BTI.

The demand on business travel is growing rapiudly. Numerous workshops, professional exhibitions, journals and websites devoted to MICE support this growth.
