Frustrated United customers say they didn't realise they were purchasing 'basic economy' tickets

United Airlines is going to great lengths to try and warn customers about the restrictions placed on its new basic economy tickets. But some of the travel booking sites like Expedia and Priceline that sell tickets for the airline are not as clear about the new fare's limitations. Since launching its basic economy tickets, United has been alerting customers before checkout about the fare's stringent limitations, such as no seat changes and no carry-ons. Customers who purchase the tickets on United's site must acknowledge that they understand the restrictions before they are allowed to purchase. The company is even sending follow-up emails to make sure that customers know what they have signed up for. However, when customers purchase basic economy seats on travel sites, the rules about basic economy seats can be easy to miss. <br/>
