Over on Wandera’s blog, they write:
Today, Wandera announced the discovery of the CardCrypt security flaw affecting sixteen companies, including four major airlines – Air Canada*, easyJet*, AirAsia and Aer Lingus*. Each of the companies has been failing one of the most basic of security requirements by not fully encrypting the traffic to the payment portion of their mobile web site or app. This means that customers who use these services unknowingly may have had their credit card information sent ‘in the clear’, and have been at risk of having that information stolen.
* UPDATE: We are pleased to say we have learned that easyJet, Chiltern Railways, San Diego Zoo, CN Tower, Aer Lingus and Air Canada have now confirmed there is no ongoing issue. We will continue to assist others in trying to swiftly resolve this issue.

Every one of the companies has exposed the full credit card number unencrypted. All of the companies, except for Air Canada, also exposed the CVV number. But the CardCrypt flaw is not limited to just this information. Alarmingly, the amount of additional information that was exposed by some of the companies has been significant and included card expiration date, full name, billing address, email addresses and even passport information.
