Nice catch on the Entertainment coupon! Indeed, with discount codes or coupons, you can often narrow the gap between airlines’ fares.

But there are three caveats for the Entertainment Book strategy:

1) The coupon is not valid on all fares, or all dates. The discount varies, depending on the base price of the ticket before taxes, and is invalid for some cheapo fares (L class, for example).

2) If you have a paper coupon, instead of an electronic code, you can’t buy the ticket online. In that case, you forfeit the 1000 online purchase bonus, and you’re no longer eligible for the double-online-bonus (500 extra if you both buy and checkin online).

3) The Entertainment book costs money, even if it’s not a lot of money. You probably make it back if you use any of the coupons, but it’s an extra expense to add to the calculation.

FYI, you can also see some of the non-travel coupons available in the book by doing a free trial, if they offer it. Here’s the link, but the trial offer comes and goes: Entertainment Book

You can also earn points on the entertainment book purchase at http://www.mypoints.com/
If you let me refer you, we will both get bonus points as well. These points can be used for various merchants.
Have a great trip!!
