For being "The voice of reason" you certainly are an idiot.
Lets talk about leg room fool. Unless your traveling First Class or Business class there is NO comparison. LUV wins hands down.
The boarding issue has for the most part been "resolved" or greatly improved. Much more relaxing. Lets see what else.
Happy employees vs ???
On time flights??
Not getting SCREWED on last minute tickets purchased
Not getting $$$ and 100$$ ti death.
Flights NOT being canceled.
Anything else you would like to add idiot?
Did you bother to assess the frequent flyer status of filejw's sister and brother-in-law?
They're likely both logging >150K miles/yr, making them 1Ks.
That means that they always sit in economy plus with the center seat blocked. That is, when they're not using their free upgrades for F. They have substantially more legroom on United than they'd have on Southwest.
As far as boarding, they are the first to board the plane.
As 1Ks, they don't get nickeled and dimed to death; those fees are paid by passengers who log less than 25K miles/yr on United.
On time flights? Where do you come up with this? While Southwest's on time performance is better than United's (Southwest has a big advantage because they don't have all of the flow control issues into busy airports), Southwest's on time performance is around 80%.
Not getting screwed on last minute tickets? What, do you really think that Southwest is priced differently? As someone who's actually priced out and purchased a ton of tickets, I can tell you that Southwest's pricing model is no different than any other airline.
Cancelled flights? Southwest never cancels flights? Have you forgotten about their overdue inspections that resulted in grounding quite a few aircraft and cancelling flights? Southwest isn't immune from cancelling flights.
In my military job, I logged >125K miles on United in each of the last couple of years. Once you achieve 1K status, you are treated very well. There are a few occasions that you aren't, but it's very rare.
Since the original poster's family is flying out of SEA, DEN, and SoCal, the only LOGICAL choice is to fly United, as United is the only legacy that has hubs in all of those cities.
As for the suggestion that they fly Southwest, I suspect that they'd give a huge thumbs down to that prospect. The customer service that they receive with United is likely not an issue; if they receive the same customer service that I've received as a 1K, they're happy with United's customer service.
And they are likely have memberships to United's Red Carpet Club lounges. Last I checked, Southwest does not offer that service. Having used the Red Carpet Club on multiple occasions, I can definitely say that it's a very nice perk.
