Uefa said its "recent experience" with finals in "comparable venues" meant "the number of finalists' supporters requesting tickets for a Uefa Europa League final can vary greatly from club to club".
"Of course, it is impossible to predict in advance which clubs will reach the final while the venue has to be chosen around two years in advance," it said in a statement.
"Taking into consideration the above and most importantly the geographical location and logistical capacity of airports in and around the host city, it was deemed that around 15,000 spectators would be able to travel from abroad (this includes finalists' fans and general public), with Baku as the main hub."
It added that "offering more tickets to fans of the participating teams, without any guarantee that they would be able to arrange suitable travel to reach Baku, was therefore not a responsible option".
"Based on these circumstances, for this year's UEFA Europa League final in Baku, 6,000 tickets have been made available to each of the finalists."
It's like UEFA are actively trying to piss off fans.
