Additionally, "[t]hrough billing, meeting, and discount eligibility codes, PNRs contain detailed information on patterns of association between travelers. PNRs can contain religious meal preferences and special service requests that describe details of physical and medical conditions (e.g., "Uses wheelchair, can control bowels and bladder") – categories of information that have special protected status in the European Union and some other countries as “sensitive” personal data.”[5][6] Despite the sensitive character of the information they contain, PNRs are generally not recognized as deserving the same privacy protection afforded to medical and financial records. Instead, they are treated as a form of commercial transaction data.[5]
