The Luton News looks back to when the Hatters won the newly-created League One back in 2004-05 to see how they have got one.
So far, only one side has gone straight up to the Premier League, while four have finished below the dreaded dotted line, ensuring their stay was a brief one.
Find out who below!
The Latics edged out Blackburn to finish as champions and went on to avoid relegation by 12 points last season. Survival was based on strong home form with 11 wins and just four defeats at the DW Stadium.
The Blades easily won League One, finishing 14 points ahead of Bolton. Excellent first season in the Championship saw them six points off the play-offs, but definitely outdid that last year, winning promotion to the Premier League.
The Latics edged out Burton and Walsall to take the title, but their stay in the Championship was a fleeting one. Relegated back to League One after ending nine points adrift of Nottingham Forest with just 10 wins to their name.
Almost reached 100 points in seeing off MK Dons for the title, one short on 99. Solid campaign in the Championship as seven home wins and six away triumphs saw them 12 clear of the drop zone.
After racking up 103 points to canter to the League One title, Wolves finished seventh the next season, just goal difference separating them from the play-off. No stopping them three years later as then went straight up.
Topped the table by a point from Bournemouth, but couldn't ensure survival in the Championship. Went down, albeit only on goal difference, Birmingham City staying up instead.
Big winners of League One and they too pushed on in their higher surroundings, enying a ninth place finish, only three points away from the top six as well. Ready for another crack this term.
After edging past Southampton for the League One title, Brighton came a respectable 10th, some way off the play-offs. Did see the Saints come second again to earn back-to-back promotions.
Beat Leeds to the title in League One and then went straight through to the Championship, finishing second to QPR and four points clear of Swansea. Back there again this term too.
Too strong for Peterborough as they won League One and then had a fine year in the Championship, ending in the play-offs. Couldn't go back to back though, Blackpool clinching promotion at Wembley.
Threatened to break into the top six after winning League One from Nottingham Forest the season before. Just couldn't muster enough points, finishing six behind Preston.
Broke 90 points on their way to the title but struggled in the Championship, particularly away from home, suffering 14 defeats on the road as they went down, ending seven points below Coventry City.
The Shrimpers won a close-run League One title race, but couldn't match that form in the second tier. Only won 10 games all year, finishing below Hull and going down with both Luton and Leeds.
After smashing their way to the title some 19 points clear of third place Tranmere, Luton made a more than solid fist of life in the Championship to finish 10th. Lack of away goals, just the 21, prevented them climbing even higher.
