Subway has established itself as one of the leading fast-food chains in Malaysia by offering customizable sandwiches and promoting a fresh, healthy image. However, customer satisfaction in the fast-food sector is shaped by multiple factors, including price, product quality, promotional effectiveness, and perceived convenience, all of which determine customer loyalty and competitiveness. This study aims to investigate how these factors influence satisfaction with Subway in Malaysia. Data were collected from 110 respondents through an online survey distributed via Google Forms and analyzed using SPSS regression analysis. The results demonstrate that perceived convenience (β = 0.459, p 0.05) and promotion (β = 0.043, p > 0.05) showed no significant effect, indicating that customers may treat them as standard expectations rather than decisive factors. These findings suggest that Subway should prioritize improving convenience through efficient service channels and digital solutions while maintaining competitive pricing strategies. Innovations in product and promotion remain important to sustain differentiation and strengthen long-term customer loyalty
