Good bargains, but why do they do the snarky 99¢ routine in their ads? Actually, the $99.99 one-way price quotes are before taxes and other charges. Why not reveal the real, out-of-pocket costs? Compared to most other airlines, they’re still a great bargain.

Taxes add another $50. The return flight is about $120. Checked bags could add another $50. Buy a seat upgrade: $20. For example, a total WOW round trip from Boston to Reykjavik may cost $400, not bad when compared with major airline lowest rate averages of $1,500.
