Launch from the Baikonur Cosmodrome; landing 135 km north of Arkalyk. The launch was delayed three days of unspecified cause.

Soyuz 28 marked the first Interkosmos mission with a foreign cosmonaut on board. The Czechoslovakian Vladimir Remek became the first cosmonaut of his country. Aleksei Gubarev and Vladimir Remek, the first non-Soviet, non-American to travel to space, were launched aboard Soyuz 28 on March 02, 1978, after a three-day delay of unspecified cause.

Following a one day solo flight Soyuz 28 docked with the Salyut 6 space station on March 03, 1978. The visiting cosmonauts were greeted by the first resident crew Georgi Grechko and Yuri Romanenko who had arrived on Soyuz 26 in December 1977. Aleksei Gubarev and Georgi Grechko had previously flown together on Soyuz 17 to the Salyut 4 space station in 1975.

Interkosmos missions had mainly political purposes but also some scientific experiments were performed, including one which monitored the growth of Chlorella seaweed in zero gravity, another which used the on-board Splav furnace to melt glass, lead, silver and copper chlorides, and an experiment called Oxymeter which measured oxygen in human tissue. Vladimir Remek's experiment program touched on life sciences, materials processing, and upper atmosphere research.

On March 10, 1978, the Soyuz 28 crew prepared for their return to Earth, packing experiments and testing systems. They undocked from the station and landed 135 km north of Arkalyk later that day
