Hello everyone,

I hope you're all doing well. I'm reaching out because I have a little issue and was hoping for some advice. I booked a flight for three people, but now a fourth person wants to join us on the trip. Unfortunately, I've already contacted Expedia, and they informed me that they can't add an extra passenger, and I'm also unable to locate the flight anymore.

I've been considering booking the same flight through RIO, but the problem is that Expedia has informed me that I can't cancel the previously booked flight and rebook it while still receiving a refund for the ticket.

Do any of you have any ideas or solutions to this problem? Would it be best to contact the airline directly or do you now if I could change the end destination from GRU to GIG?

Thank you all for your help in advance.
