Kulula.com has recently added Passbook integration into their mobile check-in. Travellers can add their boarding pass into Passbook on their iPhone or iPad.
South Africa Airways and British Airways (Comair) already support Passbook integration however Kulula.com previously used a jpeg format as seen below.
South African companies have been slow to adopt the technology available in Passbook with only SAA, BA and now Kulula offering support.
If you know of any other companies offering Passbook support in South Africa let us know by commenting below.
