While traveling in the British Virgin Islands, I plan to use my iPhone 6S Plus and my iPAD.  My plan includes TravelPass coverage ($10 per device per day) for my iPhone only.  I plan to use my iPAD, set to Airplane Mode, for WIFI using my iPhone6S Plus as a hotpot.  My expectation is this will eliminate the need to add additional Travel Pass coverage for my iPAD.  Can anyone confirm for me whether this is correct or not?  Thanks.
