Counterpoint: I had never heard of OneTravel and now in a little while I will have forgotten about this incident, but the name recognition will still exist for me, and therefore I'm more likely to trust them.
I don't think this lines up with memory research. It's true that people commonly make source monitoring errors, but generally feeling negative affect toward something enhances memory. People might forget the specific company, but I doubt they would feel more trust toward travel companies in general.
