Matches in the second league in Białystok were already averaging 15 thousand viewers. The first match in the return to Ekstraklasa had estimated 35-40 thousand supporters. Every home match following the first was viewed by no less than 20 thousand fans in the stands. Stories from witnesses said they recall buses of supporters come from villages all over the region. The first few seasons did not turn out well for the Białystok team as they finished 8th twice and then 16th, which meant they were relegated. A year later the team lost the playoffs for promotion in a penalty shoot-out against Zagłębie Sosnowiec. In the following year Jagiellonia finished 2nd place earning them promotion to the Ekstraklasa. After only one season in the first league the team was significantly outclassed and were relegated, where they continued to fall to the 4th league. They did not spend much time in the bottom tiers; within 3 years Jagiellonia was back in the second league.
