When flying across the international date line, it is possible to experience Jum'ah twice a week. For example, using JQ3, one can leave Sydney on Friday 6pm and arrive in Honolulu on Friday 7am. So he can travel after performing Jum'ah and when he arrive, it is time for Jum'ah again. Has there been any ruling on whether there is obligation to pray twice, or is it ok to choose either Friday?
Bonus: Conversely, it is also possible to completely miss a Friday noon by travelling in the opposite direction, e.g. with JQ4 one can leave Hawaii on Thursday morning and arrive in Sydney Friday afternoon, even though it's just a 10 hours' flight
