When does the infight wifi refresh

My guess is every flight since I used my hour on my return flight even though I used an hour on my flight to Chicago.

Yeah I understand that the 1 hr ones are unlimited. Cuz I've used those ones a lot. Yet the FULL session ones which gives you only 4 doesn't show the fresh time nor does t-mobile show any thing one when it does refresh. I went on a fight for 4 hrs and used it back and forth which left me 2/4. Now I used another one. So next year will it refresh or what's the deal?

Maybe @HeavenM the helpful community manager can shed some light on this.

Hey there @Ju5t It is key to understand exactly when benefits start over so you know when you can take full advantage. The four full sessions are on a calendar year rotation so they will refresh in January. 

Thank you! Finally someone  

Thank you for this answer @HeavenM ! I was looking for the same. One follow-up question, do you get 4 four-hour sessions PLUS unlimited 1-hour sessions per calendar year, or is it 4 four-hour sessions OR unlimited 1-hour sessions?
