BTR,
I see that you are a UA-1K. I'm a former one myself and have been flying Frontier for several years now as their top-tier, Summit. I must admit, it's terribly tough to give up that level of status for any other airline. But, here's why I fly Frontier.
- Friendliness of cabin crew
- Ease of attaining top tier FF status
- Free Live television
- Free premium drinks or bottle of water
- Very good on-time performance record
- Newer planes
- A Concourse at DIA
- Good prices that are almost always cheaper than UA
Here's what I miss about UA.
- Perks of 1K FF status
- First class seat
- Solid international route network
- Great FF aliance
- Route frequency
In the end, it's the little things that won me over to Frontier. They are professional, caring, and courteous to their customers. They listen to customer feedback and actually acknowledge it. And, as the Milwaukee flyers can tell you, they serve a pretty good cookie on each flight after 10a.
Since you brought it up, I wanted to take a brief moment to address IRROPS. Since you're a big flyer to Colorado, you know the likelihood of this occurring. I have found that Frontier handles it about as well as anyone else. However, if we get one of those storms that pounds for a couple of days, Frontier is not as prepared IMO, because they don't have as much personnel. So, keep that in mind before you switch, because with your 1K status, you get immediate attention at UA. At Frontier, you could wait for hours on end in the rare instance of a major disruption.
