Atletico Madrid fans will travel in their thousands for their UEFA Champions League quarter-final second leg at Borussia Dortmund on April 16.
Los Rojiblancos host the Bundesliga giants on April 10 before heading to Germany for the return leg the following week.
The club had already agreed to a plan to subsidize flights from Madrid, and paying €200 per person for 1,000 chartered plane tickets to Dortmund, as part of an effort to boost supporter numbers.
However, the enthusiasm of the Atletico faithful meant that demand far outstripped supply in terms of match tickets ahead of a big clash at Signal Iduna Park.
According to reports from The sports worldthe club easily sold out its 3,800 UEFA-sanctioned allocation for the match, but had requests from 5,700 fans to make the trip.
Despite the option of bringing in more visiting fans, Dortmund have rejected the possibility of increasing the away end as they are confident of filling the rest of the ground's capacity of 81,365 with home supporters.
