I was surprised flying American Airlines this week that the onboard credit card pitch for the Barclays AAdvantage® AviatorTM Red World Elite Mastercard® included the flight attendant noting that this is ‘a new card introduced in 2017 (sic) and that if you already have the American Airlines card issued by Citi you can get this one too.’
Explicitly mentioning a competitor product seems to be a new part of the script since I’ve seen several references to this from other flyers on Facebook as well.
