As it relates to advance schedule, it is challenging, especially to/from smaller cities when one books a flight and makes plans around that flight, when there is little intention to operate it. I just recently booked a fight from a small city to LIH on a double connection through DEN. If the flight isn’t likely to operate, it would be nice to know with a little advance notice so I can reconsider my options, which might include staying over a night on the west coast. Obviously, there are other pieces that have to be locked in like hotel rooms, some of which are asking for non refundable guarantees in this strange post-COVID environment.
I was burnt by United just after the holidays on a similar situation. I booked 2p flight from small city to Chicago about 6-8 weeks out, only to have them cancel all but the 6a flight in a schedule change. Meanwhile AA was operating 2-3 times a day. If I would have known, I would have booked AA in the first place. Moreover, I was honestly really ticked that I was put in this position, which doesn’t do well for my thoughts on UA in general.
If you don't mind which small city are you traveling from and can you provide a date in which you are looking to travel. The reason I'm asking is because I've posted this response to you before late last year and again several times this year in an attempt to help you because it can be frustrating when an airline changes your travel plans.
If you don't want to provide that information that is fine but like I stated before in other post your best indicator on what will operated (lets say for example in June) is to look at which flights are operating in April and May and perhaps even look at to March. You currently have 2 full months worth of schedule loaded for April and May May's schedule was completed and published before March was over.
Now what you should not do (and I hope I'm not coming off as condescending or disrespectful) is this if you are looking to fly out on a Wednesday again using June as an example, you should be looking at Wednesday's schedule in April and May to use as a comparison or a starting point. United's flight schedule increases daily starting on Thursday, increases on Fridays, increases on Saturdays, Sundays are our busiest days, then there is a slight reduction on Mondays, and flights bottom out on Tuesday and Wednesdays. So if you are flying out on a Wednesday then don't look at a Sunday schedule for comparison look at an actual Wednesday schedule in April and May and use that schedule as your guide to what the June's schedule will look like.
United is no longer do major cuts to the schedule, meaning we are not reducing capacity we are increasing capacity because for now the industry is in an upswing. What does that mean for you, that means even if for the month of April and May (both schedules are 100% complete) United only has a 6 am flight and you book that 6 am flight for your travel needs in June and United decides to add a 9 am flight when they post the June schedule you haven't lost anything. You can still take that 9 am flight and shorten your connection time because now you have the ability to do same day standby for free. And United recently announced they will now refund passengers the difference if the 9 am flight is cheaper than the 6 am instead of keeping the change.
We all are adults here we all know we are still in a pandemic there are ways for you to figure out what the future schedule will be and make your decision to purchase or not to purchase a ticket based on that information.
