Startup Idea: Airline Ticket Management App

Startup idea to develop an app that helps users manage their airfare tickets more effectively. The app would provide a platform where tickets can be bought and stored, regardless of who booked them. It would provide flight details, confirmation number and airline reminders

I fly from coast to coast on a monthly basis. I buy airfare tickets that are the cheapest available. I buy tickets with my husband, so the confirmation either gets sent to him or me. When we need to check into flights, we don't have a clear, concise ways to look up flights. Sometimes the flights are on his phone, sometimes mine. I don't remember which airline I am flying, or even a confirmation number readily available.
