Booked tickets for son & daughter to fly to Sioux Falls from Manchester involving a lay over of 5 hours at Chicago going over and 90 mins coming back. When I checked the e-mail receipt I was horrified to see the lay over was 19 HOURS going out and 6 coming back. I emailed with details of the problem and next morning got an email from their sales dept asking if I had bought for the flights I had 'browsed' the night before (including the layover times I wanted). I tried to explain my problems but when the sales person heard I had bought tickets he was very abrupt and put phone down. I got and email later from the 'admin dept' and spoke to someone who insisted I had bought the ticket with the long layover times but said he could change the tickets for ....£450! He also said it was my fault because I had booked online instead of talking to someone over the phone, oh, and there were plenty of hotels near Chicago airport so that wasn't a problem ??? PLEASE do not use this company as there is obviously some scam whereby they think they can hold you hostage in order to extract more money from you. I just hope ABTA can help me out but in the meantime DO NOT TOUCH THEM WITH A BARGEPOLE.
