Delta is selling Alaska Airlines direct flights from San Diego to Maui roundtrip for $297. And American, United, and Delta are all getting in on the sub-$370 party from Los Angeles to Hawaii roundtrip.

There have recently been a ton of great deals to Hawaii. I'm not sure the cause of the sales--tourism to Hawaii is way up this year--but I've taken advantage and been trying to get everyone else to take advantage.

The legacy carriers--United, US Airways, Delta, American--all charge a fee if you ticket your award by phone instead of online. Here's your guide to avoiding those phone fees:

United

United charges $25 per passenger if you book by phone. They will not waive this phone fee just because a booking could not be completed online. That's frustrating because many multi-city and free-oneway awards can't be booked online. They generate error messages despite being within the routing rules.

Here's how you avoid the phone fee with United:

First, search for and reserve any United flight.

US Airways miles stink because their routing rules and fees are frustrating.

But US Airways miles are incredible because the award chart is so generous. I've talked about sweet spots here and here.

Overall, the sweet spots on the award chart and US Airways off peak awards more than make up for the routing restrictions, so I value US Airways miles more highly than any other airline mile at 1.95 cents each.

If you use US Airways miles correctly, you can reap incredible value.

US Airways and American Airlines have merged since the publication of this post, so it is no longer valid. Click here for the top current credit card sign up bonuses.

Christmas Cutbacks from United and How to Deal With Them

The holidays are bringing some unfortunate consequences for people who book award flights on United around Thanksgiving, Christmas, and New Years, as seen in this FlyerTalk thread.

In January, I booked an award

Hey there, you're reading an outdated post! The updated series from April 2015 can be found here.

This is the twenty-third post in a monthlong series. Each post will take about two minutes to read and may include an action item that takes the reader another two minutes to complete.

Bad news for anyone who wants to book awards to the Middle East, the Indian subcontinent, the Maldives, and even Europe with United miles.

United's relationship with Qatar Airways ends September 14. Tickets booked by then can include Qatar segments up to 337 days out or so, which is generally how far in advance you can book United awards.

Yesterday I talked about some great sweet spots on the US Airways chart for awards originating in South America. Maybe you thought that post was irrelevant for Americans.

But Americans can still get half the value of these sweet-spot awards by using open jaw itineraries.

US Airways sweet-spot awards can have tremendous value for Americans if they're employed as part of something I'll call a triangle award.

A triangle award is using three or more oneway itineraries to create a journey that includes two or more destinations.

I always like to scan award charts for sweet spots. I would define a sweet spot as one of three things:

An award that is much cheaper with one airline's miles than another airline's miles.  In this post I'll talk about EZE-BOG, CLO-BOG-EZE in Avianca business class costing 30k US Airways miles vs. 80k United miles.
An award that is much cheaper than a slightly different award on the same airline. And ideally the sweet spot award can be turned into the highly similar award cheaply.
