Flaño was born in Pamplona. A product of hometown CA Osasuna's youth ranks, he made his first-team debut on 18 September 2004 in a 3–2 La Liga home win against Real Betis, finishing his debut season with eight games. Aged only 17, he began playing regularly with the B-side in the third division.
From then on, Flaño became an essential defensive fixture with the side as twin brother Javier, who had been a starter from 2005 to 2007, gradually lost his importance, leaving after the 2008–09 campaign, where Miguel netted four times in 33 matches in an eventual narrow escape from relegation. He eventually renewed his link in August 2009, running until 2013.
On 7 June 2012, Flaño again extended his contract with Osasuna, now until 2017. In 2015–16, he started in all his 34 league appearances to help the club return to the top flight after a two-year absence.
In the early stages of the following season, both siblings suffered a complete rupture of the anterior cruciate ligament on their left knee, being sidelined for several months. In the following years he was only a backup option, featuring rarely.
