I'm looking to book a trip from IAH-PHL in two weeks. The lowest fare (2/21 to 2/24) looks to be 233.00 in I Class.

A couple questions....

1) Any promo codes that I could benefit from? I do not have the Continental Credit Card, but do have other Visa/MC/Amex.

2) Is there any way to check other fare classes on continental.com? It seems that the "I" fares are the only ones I get back.
