Sales begin at 9.30am on Wednesday, March 25, for season ticket holders who have attended 20 or more away matches across the 2024/25 and 2025/26 seasons.
Further sales windows will then open in stages over the following days, gradually including supporters with lower away attendance totals, before a window for season members on Monday, April 6, subject to availability.
Official coach travel has been priced at £50 per person, with a £2 discount for season ticket holders, with departures scheduled from St Mary’s, Eastleigh, Winchester and Chieveley.

Swansea is one of only three away trips left this season for Tonda Eckert’s side, with Wrexham earlier in April and Preston on the final day of the campaign.
