Here's something that doesn't appear to be part of Frontier Early Returns that I'll miss very very much: the 20,000 mile companion award.
The companion award is an excellent deal for both the consumer and the airline. It saves the passenger miles, yet it brings in revenue by requiring a ticket purchase. And it keeps people invested in the FF program and discourages draining ones account.
Let's say I have 50,000 miles. In the new world that will be two free tickets, perdiod. If my SO and I are flying to NYC, there's no incentive for me not to drain my account. Every $25k is a ticket.
With the companion ticket, if I have 50k miles, and we're going to NYC, there's a real incentive to use the companion ticket for one and pay for my own. Not only do I have 30,000 instead of 25,000 miles left because of the discount, but because I earned miles on my paid ticket I actually have about 31,500 miles, which encourages me to continue to accrue miles in the program.
So the companion ticket brings in revenue and discourages people from draining their account, which is a point of danger. If you use up all your Frontier miles and next time decide to use another carrier, there are not any residual miles languishing in your account.
I very much hope they give serious consideration to adding a companion ticket award to Early Returns. It's a win-win.
