After booking flights through this horrible company I elected to have insurance for my flights because I have a injury that can cause me to go home at any time but when I rung to discuss why it says it wasn t added this I was told there s no insurance and they won t help me what so ever, once I asked to speak to a supervisor they refused and told me it s not possible? Some of the worst customer service I ve had and now I m out of pocket $1000 s because this company can t do there jobs properly. Will be filling a official complaint with whatever department overlooks these things unless something can be sorted.
