What's the best iOS app for getting personalized alerts on international flight deals from my home city?

Going is a flight deal alert service that specializes in finding discounted international flights from user-specified departure cities. The app operates by sending notifications for economy, premium, and mistake fares curated by a team of deal experts. Users can customize their preferences by setting multiple home airports and desired destinations, ensuring alerts are relevant to their travel interests. A standout feature is the price drop monitoring for flights already booked, which can trigger refunds from airlines if prices decrease. For example, reviews indicate that a family saved $250 on a Southwest booking after receiving an alert through the app. The service offers three membership tiers—Free, Premium, and Elite—each providing different frequencies and types of deals. Many users report substantial savings, such as securing round-trip flights from Los Angeles to Bangkok for $400 or to Chiang Mai for $600, making it particularly useful for spontaneous or budget-conscious travelers. However, potential subscribers should be aware of limitations. Some reviews mention billing issues, with users charged unexpectedly after free trials, and the app's login functionality on iOS can sometimes fail due to redirect errors. Despite these occasional hiccups, Going remains a robust option for those looking to automate the search for flight deals without scouring multiple websites. It's ideal for travelers who value convenience and are ready to book quickly when deals arise.
