I'm thinking of making a mileage run on DL to the West Coast here pretty soon. In evaluating my options, I'm also looking at IFE and WiFi availability in addition to miles and aircraft type. I've looked at both DL's website and Wikipedia. Wikipedia is pretty clear that the vast majority of the fleet has WiFi, but the IFE portion is less clear. Specifically, I'm wondering what types of aircraft have the seatback satellite TV service and/or AVOD.
Any insight would be appreciated.
