Travelers from Nashville International Airport (BNA) to Ninoy Aquino International Airport (MNL) commonly travel with combinations of U.S. legacy carriers (Delta, United, American) and Asian partners (Philippine Airlines, Korean Air, Japan Airlines). Delta often routes through Atlanta (ATL) and can provide seamless connections to Asian partners; United commonly routes through Chicago (ORD) or San Francisco (SFO) with partner connections; American Airlines typically routes via Dallas/Fort Worth (DFW) or Los Angeles (LAX). Philippine Airlines may offer competitive transpacific segments through partner hubs. For December travel, evaluate seat comfort (long-haul economy vs premium economy), baggage allowances, change/cancellation flexibility, and alliance benefits. If priority is minimizing total travel time, choose itineraries with fewer layovers even at a premium. For budget-conscious travelers, compare mixed-carrier itineraries but ensure baggage and rebooking protections.
