The three Royal Caribbean brands in North America (Royal Caribbean International, Celebrity and Azamara) recently introduced Choice Air for their air/sea passengers, but effective July 1, the program will offer two additional options, and the standard air/sea program (where you don't know your exact flights until close to departure) will then shortly be discontinued.
When the change is completed, the brands' air/sea programs will have changed completely.
Details appeared in the June 24, 2010, edition of Cruise News Daily.
