Virgin America recently launched non-stop service between Los Angeles/San Francisco and Newark and is offering some very attractive promotional fares, with round-trip travel starting at $198. Travel from 3 September – 30 October on Tuesday, Wednesday or Saturday at this low price level. United Airlines has matched (and N-class does earn 100% credit in the MileagePlus program).
This deal will be gone by the end of the day, so book sooner rather than later. Both Virgin and United offer a risk-free 24-hour courtesy cancellation period after booking.
