Is there a good Android app that helps with Delta Air Lines elite status perks and booking management?

Fly Delta is a comprehensive mobile tool for Delta Air Lines passengers, particularly those with elite status or frequent travel needs. The app integrates SkyMiles accounts, allowing users to view and redeem miles, track elite status progress, and access exclusive offers. For real-world scenarios, such as a business traveler needing last-minute flight adjustments or lounge entry, the app provides features like mobile boarding passes, flight status updates, and Sky Club location details. Users can check in, select seats, and receive gate change notifications directly on their devices. Reviews indicate that the app mirrors most website functionalities, making it reliable for handling ticket refunds and exchanges without ads or login hassles. However, some limitations exist; for instance, companion certificates often do not work within the app, necessitating a shift to the desktop site. Users also report occasional slowdowns, errors, or freezes during peak usage times, which can disrupt smooth travel planning. Despite these minor imperfections, the app excels in consolidating travel essentials, such as displaying arrival gates and managing bookings, though feature requests like automatic SkyClub Wi-Fi login or in-app seat volunteering remain unaddressed. Overall, Fly Delta balances convenience with robust airline-specific tools, albeit with room for incremental improvements.
