From Stan Diego you really don't have a lot of good options, AA via CLT or MIA which is probably the best or DL via ATL or JFK. Jet Blue might not be a bad option as you could connect via FLL, or could do JFK or BOS I think from SAN. Life on the Left Coast!

We are going Alaska (I have status with them) to JFK on the red eye then going down to SXM on JB. We don't mind the red eye going to SXM as it is better than just traveling all day and landing in the evening or spending a night along the way. We adjust to the time zone change pretty fast doing it this way as well.

Good luck!
