Following pre-entertainment on the stage from a local band starting at 11am, the main party will kick off when Hatters players and officials arrive in St George's Square from Kenilworth Road in an open-top bus at around 12.15pm, before joining the Mayor onto a stage for short celebratory speeches hosted by BBC Three Counties Radio.
The team and officials will then make their way to a private reception in the Town Hall, with season highlights playing on large screens in the Square until 2pm.
Cllr Ayub said: "It has been a monumental year – on and off the pitch – for Luton Town Football Club. Not only have they had another outstanding season and achieved back to back promotions, but they've also got the seal of approval for a new stadium at Power Court, marking a big step in the club's history and their ambitions for the future.
"I'd like to offer the team, staff and all the fans my congratulations and I would like to warmly invite the club's supporters and everyone in Luton along to the event so we can all come together in celebrating their success."
Laura Church, Luton Council's Interim Chief Executive, added: "We are all absolutely delighted with Luton Town securing another promotion in what has been an incredible season. We know how much this means to the supporters and the town as a whole.
"When Luton Town does well, the whole town does well, and promotion to the Championship will ensure a fantastic vibe across Luton for the foreseeable future and a positive boost to the economy next season. I look forward to seeing as many people as possible on Sunday."
The open-top bus tour will depart Kenilworth Road at around 12noon and proceed to St George's Square at walking pace via Dunstable Road, Telford Way, and Manchester Street.
In order to aid safe and smooth running of the event, the following roads will be closed from 9am-3pm: Guildford Street, Bridge Street, Gordon Street, Alma Street, Alma Link, Manchester Street, George Street, Upper George Street, Wellington Street, Dunstable Place, New Bedford Road (jct. with Luton-Dunstable Busway) and Oak Road.
Motorists are advised to plan alternative routes around the area between those times.
The day's event is being funded by the council's airport company, London Luton Airport Limited, to acknowledge the support that the airport receives from the people of Luton.
