Delta has certainly picked a poor time to make changes. With that said, how does one find out the class of service for tickets already booked for next year. Since, they are already upgraded they show up as X and V fares-not on the chart. Secondly, how can one choose the Fare Class on the website? Presently it is all or nothing. Frequently, if a segment's upgrades are gone or otherwise not available, the website will not let you book an upgradeable fare. Lastly, am I correct in assuming that one will still earn miles at the current rates, it is just the qualifying that is changing?
