The lack of headphones impacted our ability to enjoy the entertainment system provided. The fact that my last connection was associated with an "affiliated airline" that did not allow me to retrieve a check in or a boarding pass via the app almost posed a significant issue as the last leg of the flight was overbooked and we were stressed about getting a seat as a result.
