that the employee asked for documented proof of her relationship to her son because they have different last names.

She also said that another mother traveling through the airport with her child was not asked for extra documentation, even though they also have different last names.

"Not shockingly, not a miked race fam," Gottlieb tweeted.

She added that she has traveled with her son “over 50 times” before and this discussion almost made them miss their flight.

According to The Washington Post, Southwest Airlines officials reached out to Gottlieb to address her concerns and apologized if "our interaction made this family uncomfortable."

Airline officials added that it is airline policy to verify a child’s birth certificate or passport if they are under the age of 2, but employees aren’t required to match the names of a guardian and child for domestic flights.

Gottlieb said she hopes this brings awareness to others about respecting “non-traditional” families.
