Question for those who have upgraded from the Explorer card: How long did it take to receive your new card and benefits after upgrading? My plan is to upgrade to the Club card the first week of May (my 1 year anniversary), as I have several trips coming up and would love to have the Club card benefits. Would I receive the new card & benefits within a week? It sounds like new accounts have had their welcome kits shipped via expedited delivery, but I'm not sure about upgraded accounts.
