mobile application – How conduct benchmarking for travel app notifications

In order to improve our airline travel booking apps notification experience, i’m conducting a benchmarking research 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.

My questions is, is there any other way i would be able to get to see these notifications?
