The topbonus number must be specified at time of reservation or rental to qualify for miles and must be the main renters number. Only one topbonus member by renting gets credited miles. The offer is valid worldwide at participating Alamo stations. Third party brokers, tour operators and certain corporate accounts can not accrue miles. Miles appear about 6 to 8 weeks after the end of the lease on your topbonus mileage account. Additional miles, awards or bonus offers are subject to the terms of the topbonus Programme.
