mobile application – How to benchmark others’ apps without expensive purchases

In order to improve our airline travel booking app’s notification experience, I’m conducting a benchmarking study where I hope to look at the various notifications at different points of the user journey (e.g. online check-in open, miles have been added, change of flight time).

However, in order to see these notifications in other airline travel booking apps, I would need to actually purchase tickets from these airlines.

Is there any other way I might be able to get to see these notifications?
