Traveler's aid, familiarly

TRIPLEA

Think of a well-known organization that offers roadside assistance and has a three-letter acronym often seen on membership cards.

"Traveler's aid" hints at something helpful on a journey, like a travel guide or map. The key here is "familiarly"—it’s a playful nod to Triple A, the common nickname for the American Automobile Association (AAA), which provides roadside assistance and travel services. The answer is written as TRIPLEA to match the crossword’s fill, dropping the spaces for brevity."
