My elderly (80 and 78) parents are traveling to EZE this fall en route to Ushuaia for an Antarctic cruise. I haven’t been down there since 2016 so my familiarity is rusty, plus it appears that EZE itself has been going through some changes lately. A couple of questions:

- What’s the most comfortable business class flight (starting in EWR, so a connection in MIA, IAH, ATL, or PTY, it seems)? Any with lie-flat seats? They don’t want to pay up for F, but they will do business.

- Suggestions for a greeter service to pick them up at EZE? They’ll be staying a night in BsAs before heading to AEP for their flight to USH. I might even suggest that they hire someone to accompany them to AEP. They are not travel novices by any means, but my mom is a very anxious person in general and also in early stages of cognitive decline, so I’d like to make the way as smooth/guided as possible. (When I did the same trip in 2016, I got to AEP only to discover that my Aerolineas Argentinas flight had been rescheduled to two hours earlier, with no notification, and I had to do some negotiating at the counter to get on a later flight that day—that sort of experience would send my mom into a tailspin.)

Thanks in advance for any help you can provide!
