I tried to change my flight dates 10 minutes after I had booked it. Travelup told me it would cost £318 per person (the flights were £286 per person), although this fee was partly from BA, I am extremely disappointed that Travelup were charging admin fees when I was so quick to contact them asking for the adjustment. Usually there is a 24 hour grace period, but Travelup give you zero. The end result - I've lost all my money bar £40 and can no longer go on the trip as the cheapest option for me was to cancel the flights. I had saved for for the trip for ages to see a friend, but now I can't go and I've lost nearly £600.
