MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document is disguised as an 'Amadeus altea reservation manual' but contains a large number of external links, as indicated by the PDF_SEO_LINK_FARM heuristic. These links likely lead to malicious content or are part of an SEO spam campaign. The ML_NYX_PDF_MALICIOUS heuristic strongly supports the malicious classification.
