Booked in 2017. Their first mistake was to give me 2 tickets-luckily they hadn't charged for 2 though their staff seemed unaware of this and I was told a refund would take 8 weeks...Well just one day before my flight of January 24th I was told it had been cancelled [rather like what happened to other reviewers]. I was able to book with Sansa and have nothing but praise for the latter company. My advice to visitors is to fly with Sansa who are efficient, pleasant and punctual. I was told by Natureair on 4th February I would receive my refund in about 4 weeks. Despite being reassured several times since then I have received nothing and they are no longer answering my polite emails. One employee told me last week to contact my bank about the matter, though I wonder what they can do at this stage.
