This is for 2 Sri Lankan nationals, no check in luggage, traveling with normal Sri Lankan passports, and transiting without VISAs. We need to get to Bahamas. They will have enough connection time (literally walking from one gate to the other in the same terminal) and we will have all RT PCR requirements met. I've checked the history of the flights and they are all usually 100% on time and not cancelled.
They will get ALL of the boarding passes in CMB through mobile check in prior to start of the journey.
We have the following flight route single ticket sold by Emirates (confirmed it is single ticket):
03/26: CMB (02:55) to DXB (05:55) via Emirates
03/26: DXB (09:05) to GRU (17:20) via Emirates
03/27: GRU (01:52) to PTY (06:40) via COPA CM702
We also have the following route from GRU to NAS (confirmed single ticket):
03/27: GRU (01:52) to PTY (06:40) via COPA CM702
03/27: PTY (07:48) to NAS (11:42) via COPA CM196
We can also get a single ticket:
03/27: PTY (07:48) to NAS (11:42) via COPA CM196
My question is this:
Brazil requires proof of evidence of onward travel in a single ticket. OK, this is satisfy by both tickets above.
Panama requires proof evidence of onward travel and in some stories online, they just need to see a ticket out of Panama even if it's a separate ticket. Based on all the evidence I gathered, it seems Panama doesn't really care about single or separate tickets.
In case they want a single ticket, having an additional ticket bought through COPA from GRU to NAS would satisfy this this requirement.
The problem is, if I bought the additional ticket, the same 2 passengers are registered on the same flight twice (GRU to PTY via CM702 flight). They will get boarding passes for both routes 24 hours before the journey starts (COPA might not let mobile checkin for Emirates originating ticket though). Also, with these 2 tickets, we will be not showing up for one ticket (emirates) in GRU to PTY even though we mobile check in.
Is that OK? Since COPA might not allow mobile check in when the originating airline is different (emirates), we can just dump the Emirates part of GRU to PTY and instead mobile check in for COPA part of GRU to PTY).
