I doubt Peach would have said anything unless the destination/location information was vetted first.
If a team is seen several hours behind other teams departing for another country, it is nearly 100% certain they are headed to sequester. Production normal separates that team upon elimination from the remaining teams, has a decompression process before sending to sequester. In past seasons, the later eliminated teams wouldn't go to sequester but travel with production, and sometimes are used as decoys on legs separated from the remaining teams. It could have changed in very recent seasons, but as far as I know, production is likely still following that pattern.
