The CAF clash between United and Celtic was postponed a few weeks ago due to the strict Covid-19 rules and regulations in Nigeria, where South Africa is regarded as a high-risk country.
CAF has since rescheduled the fixture for Benin this coming Saturday.
Celtic CEO Khumbulani Konco says the club has managed to secure a direct flight straight to Benin for the encounter.
"Everything is in order. The club left for Benin yesterday after the game against Mamelodi Sundowns and it's a direct flight," Konco tells snl24.com/kickoff.
"We have done all the preparations and we're looking forward to the game on Saturday."
Siwelele are trailing 2-0 to their Nigerian counterparts after losing the first leg in Bloemfontein late last year.
