TWA used two doors to board its 747s; L1 for First and Business class passengers and L2 for Economy passengers. On my recent A380 flight, BA used three jet bridges for boarding at LHR, two for the lower deck, one for First and Business class passengers and the other for Economy passengers, and the third for the upper deck (Business, Premium Economy and Economy).
