ULR Flight DEL to EWR lady moves upfront to J as soon as we departed... When FA approached her she claimed her legs were hurting and she was cramping and was unwell and needed to stretch out.
FA got her a glass of water and told her that the water would make her feel better or we would need to land asap and get her medical assistance. Closest airport at that time was Islamabad....
Glass of water fixed her ailments!
