We are booked for a Caribbean sailing in November with the included air. We normally do our own air, but getting from Austin to Barbados is a bit of challenge, so we thought we might have Silversea do this. When can you request air schedules and book flights? Can you request specific flights? What is the air deviation fee, as we will be going to Barbados a couple of days early? Any suggestions or experiences you've had with their air would be greatly appreciated.
