Ms Jobling and her husband were holidaying with another couple, Paula and Nicholas Mason, also from Hull.
The Masons returned home on 12 June – the day both couples were meant to fly back together.
Ms Mason previously said her friend looked “really healthy” in photographs taken at the start of the break, which was booked by the two husbands as a surprise for their wives.
Ms Keita said she dashed to Crete to see her aunt when she was taken ill. She plans to return once Ms Jobling’s European Health Insurance Card, ordered prior to the holiday, arrives.
“The doctors say they need it,” she said. “Fortunately, Donna also took out holiday insurance.”
