You can use your A1 bonus by making several shorter trips.
If you travel more than 1 hour
After your trip exceeds 1 hour, the per-minute and per-kilometer rates according to the plan you have chosen - Standard, SPARK Pro, Recharged, or Supercharged - will be applied.
If you travel less than 1 hour per month
If your total trips for the month are less than 1 hour, unused minutes are not carried over to the next month. According to A1 rules, SPARK cannot compensate you for unused time.
