12:05am Another great deal! SFO-Cancun on Mexicana Airlines. Fare Basis: EL14RSS. Price is $104 rt + tax, making it just $202. Visit http://www.mexicana.com/ to book. This price is valid 7 days a week through the 2008 schedule. Supersaver Fare, no changes permitted. It's possible you do not earn frequent flier miles either. Still a great price for Spring Breakers, or just a nice weekend getaway. Book soon!
