What TAP Air Portugal Is
TAP Air Portugal is an airline, not a retailer or bank, so the site is mainly used for booking flights, checking travel information, and managing reservations. The domain was first registered in 1999, which is a strong sign of long-term ownership rather than a throwaway site. HTTPS is enabled, so your browser can encrypt the connection while you browse or book.
Reputation and Verdict
TAP is a well-known national carrier with a real-world travel operation, so the brand itself is not suspicious. The main risks are the usual ones for airline websites: lookalike pages, booking mistakes, and payment issues during peak travel periods. Overall, flytap.com looks consistent with a legitimate airline domain, and the age of the registration adds confidence.
