For the frequent traveler who is loyal to an airline, a lot of those problems go away.
We are Delta loyalists and both Platinum Medallion.
1. When we buy a main cabin seat, we get upgraded immediately to Comfort+ for free.
2. When we go to the airport, if we don’t use curbside check in (and tip), we get to use the Sky Priority Checkin line and have two free checked bags
3. We have TSA Pre-Check and Clear to skip the line
4. After check-in, we head straight to the Delta, Amex Centurion or Priority Pass lounge where we have plenty of seating free food and drinks (alcoholic and non alcoholic)
5. When boarding, we get to board early because of our C+ upgrade (Zone 3) or worse case Zone 4 and have plenty of overhead space if we need it and get to be situated early.
