Millwall will travel 6,742 miles over the course of the 2019/20 Sky Bet Championship campaign.
Norwich City, Sheffield United and Aston Villa have departed for the Premier League after winning promotion in 2018/19, whilst Rotherham United, Bolton Wanderers and Ipswich Town will play their football in Sky Bet League One following relegation.
Meanwhile, Cardiff City, Fulham and Huddersfield Town join the second tier from the elite, with Luton Town, Barnsley and Charlton Athletic winning the chance to play in The Championship after securing promotion from the division below.
The Lions' longest trip of the year will take them to Middlesbrough, with a round trip of 514 miles when travelling from The Den to the Riverside Stadium, with the shortest journey seeing Millwall visit The Valley and Charlton Athletic - just an 11-mile hop to SE7 and back.
Oakwell (378 miles) and Kenilworth Road (115 miles) will act as new trips for the season for supporters, with the relegated trio seeing 312 (Cardiff), 426 (Huddersfield) and 19-mile (Fulham) journeys respectively.
Elsewhere, the round-trip of 412 miles to Elland Road will no doubt whet the appetite of all involved.
