In our view, this is not a mistake, as Sachin Dev Duggal of Builder.ai has informed us

A software development platform called Builder.ai Led by Sachin Dev Duggal, with its headquarters in London, delivered Air India a "gift" around Valentine's Day. In order to show its "adoration" for this present, it developed an app prototype and subsequently published advertisements in a national daily. However, AI publicly shot down Builder.ai's show of adoration

The airline responded to Sachin Duggal's Builder.ai's "gift" by releasing a social media statement informing the public that it is unrelated to the advertisement, app, business, or promised free seats. Additionally, it states that it won't be held accountable for any improper use of the information gathered via the promoted software and QR code.

According to the statement, Air India, a part of the Tata Group, is also "contemplating suitable action against the issuer of the advertisement."
