On her return flight to Atlanta, staff at the gate ensured she was upgraded to first class again.
"I am incredibly grateful for the lengths these individuals took to make my role as momma much easier, and impressed by the advocacy this company has provided for breast-feeding and pumping," she wrote.
"Thank you, Delta for making being away from my babies a bit more bearable!"
In response, Delta said, "We are very happy to hear that [flight attendants] Kaitlin and Loretta were able to be there for you when needed.
"We would love to recognise them and pass your kind words along as we know they would be very touched and happy to know this."
However, there have been many not-so-pleasant involving airlines - including Delta - and breastfeeding mothers.
In December, Sikh activist Valerie Kaur said she was left "angry and shaken and sad" after being forced to display her breast pump to "show them I wasn't a terrorist".
On a United Airlines flight earlier this month, Juliet Thomson, 28, said she was told to cover up while nursing her four-month-old daughter. Ms Thomsen said she was left in tears after being told to "put some clothes on" by a flight attendant.
Another mother, Vanessa Kasten Urango, ran into trouble flying Delta in December, when the airline refused to let her transport breast milk packed in a cooler with dry ice.
She had been previously told by the airline that this was the correct method.
Delta later apologised and offered her a voucher as compensation.
