Routing (same booking)

LIM-PTY (CM436) > at this stage, it was not possible for the agent to issue the last BP at the check-in counter (but she was able to issue the all others, all 3 with the CopaAirlines logo)
PTY-PUJ (CM241)
PUJ-YUL (AC1297) > two BP issued for this trip (the first one in LIM, with the CopaAirlines logo at the check-in counter, the second one in PUJ with the AirCanada logo at the GATE counter, remark: SIXF only on that second one)
YUL-GVA (AC884) (remark: ADOC SIXF on this one) (this BP was issued in PUJ, at the GATE counter. I was able to select my seat online for all flights, but it was impossible to check-in online for this flight, so I was not checked until the GATE agent at PUJ did this for me)
