Make sure to follow up with us on how things go. The rest of us might learn something.
Boarding generally begins 20 minutes before the scheduled departure time, so that’s about the time you’ll need to start paying closer attention.
Since this is a direct flight, there are a lot fewer things that can go wrong. I was trying to think of a “worst case” where not being able to clearly hear announcements would cause problems. In my experience there have been a few.
Gate changes - its possible your flight will be moved to a different gate for some reason. You might have a nice seat where you can see the boarding info, then an announcement is made that your flight will depart from a different gate. You’ll have to grab your stuff and shuffle off to another location.
Gate checking - some aircraft don’t have large overhead bins and there isn’t enough room for all the carry on luggage that people tend to bring. They’ll have an announcement about gate checking. You’ll get a specific tag you can put on your carry on, they’ll take it and load it in the hold. After you arrive they’ll pull it out for you and you can grab it as soon as you get off the plane.
Delays - generally posted on the information boards, but also there’s an associated announcement.
Standby - if you are on a standby list, your name might be called over the PA system.
Baggage claim - after you get off the plane there might be an announcement telling you where to find your bags.
Gate changes or other flight info - there can be announcements over the intercom that are important if you are transferring to another flight. One time I was on a flight that had been delayed, then we ran into more headwind than expected. The result was we were going to be much later at the next airport than anyone planned. An announcement was made so that passengers would know what gate they needed next when they got off the plane. “If you are transferring to xxxx city on flight zzzz, you’ll be at gate 123.” I leaned over to the closest flight attendant and asked, “What about my flight? It left 10 minutes ago?” There will be an agent waiting when you get off that will be able to help.
Enjoy the trip!
