Air Inter changed to Air Inter Europe following a merger with Air France and UTA. On 1 April 1997, it was absorbed into Air France. On that day, the firm ceased to exist as a legal entity within Groupe Air France.

(EU) during the early 1990s, Air Inter was a pillar of the French air transport industry with Air France, UTA and TAT.
During that period Air Inter had a large share of the domestic market. It was the only airline plying most of the domestic trunk routes within metropolitan France on a regular scheduled basis, especially from and to Paris. The exceptions were Paris-Nice and Paris- Basel/Mulhouse. Air Inter's flights between Paris Orly and Nice competed with Air France's Paris-Charles de Gaulle — Nice, and Orly—Nice flights. Air Inter competed head-on with

, between Paris Charles de Gaulle and Basel/Mulhouse.
The difference between the competing Air Inter and Swissair services on this route was that the former's passengers had to use the terminal at Basel/Mulhouse airport through the domestic channel that connected the airport to the French city of Mulhouse, whereas the latter's used the international channel that linked the airport with the Swiss city of Basel. For this reason, Air Inter's flights were categorised as domestic while Swissair's were international.
In addition, UTA had limited rights to carry passengers, cargo and mail on the internal legs of its long-haul services, between Paris Charles de Gaulle and Lyon, Marseille, Nice as well as Bordeaux. However, flights were too infrequent to pose a threat to Air Inter.
SNCF, one of Air Inter's two largest public sector shareholders, was also the company's main competitor on domestic trunk routes inside France. This intensified when SNCF began high-frequency high-speed train (TGV) services on purpose-built tracks from 1981. The launch of TGV services between Paris and

, one of Air Inter's busiest as well as shortest routes, in 1981 led to a reduction in frequency and smaller aircraft on Air Inter's competing service.
The only other domestic air routes on which Air Inter competed with Air France in the pre-liberalisation era were routes linking the mainland with Corsica.
In 1977, Air Inter purchased a 20% stake from Air France in the latter's charter affiliateAir Charter International, in return for ceasing to be a rival supplier of

seats in the French inclusive tour market.
Annual passenger numbers on Air Inter's domestic scheduled network grew steadily to 21 million, actually beating Air France one year. This established the firm as the largest scheduled domestic airline in Europe.
Air Inter was also one of the few European ultra short-haul, mainline scheduled operators to be profitable most of the time and was a forerunner of today's low-cost airlines in Europe. Fares were lower than domestic air fares elsewhere in Europe and competing rail fares, with short turnarounds (35 minutes for a full 314-seat A300 was common), no seat allocation,

On 1 January 1995, Air Inter lost its monopoly on the domestic trunk routes from Paris Orly. From that day, any EU-based rival was free to compete on these routes, without restrictions on capacity, frequency or fares.
