Customers can check the entertainment portal on board to see if the feature is available on that particular flight, the spokesperson said.
"When available, passengers will see a 'Free Access' button instead of a link to payment page on the messaging tab in the WiFi portal. The service is limited to iMessage and WhatsApp, and does not support sending photos."
In-flight messaging previously cost $2 on board Southwest flights, with the same text-only limitations. Full Wi-Fi capability costs $8 for all-day access, regardless of the number of flights taken that day.
