We are flying SJC---LHR---MUC in Club World/club Europe next summer (on one ticket). I have paid to choose seats for the long-haul flight but am debating about the short hop to MUC. Will we able to check in for that flight at the same time as the longhaul flight--that would be 20:05 Pacific Time on Sept. 2---or do we wait until 24 hours before the MUN flight, which would be 16:35 London time on Sept. 3?
