Possible Malware or Virus? Possible race condition based on system speed (this would be a big blunder on ExpertFlyer's part if they managed this).

Since you think it might be JavaScript related, try disabling JavaScript to see if that make a difference?

No. - They seem to be refreshing the website via JavaScript.
I guess to either keep that auth0 stuff alive or properly align their design or lazy-load other stuff.

This happens on multiple different systems and browsers.

E.g. you navigate to inventory search, quickly start typing and after 1-3 seconds your input is completely gone because they reloaded the complete website.
When you fire up developer tools you notice that they initated the reload on their own from one of their JavaScripts.

JL Information on EF not Accurate
 

I have two JL flights roundtrip HNL-HND-HNL on 10/30 (JL 71) and 11/23 (JL74). EF shows some open J seats, while JL's website shows them unavailable. .I reached out to my travel agent, and they confirmed these supposedly open seats are unavailable. ExpertFlyer Voice , any reason/fix for this?

Hi All - Quick updates on a few recent launches:

• "Keep Active" Alerts for Schedule and Aircraft Changes if you opt for it, these alerts will now continue notifying you through departure rather than triggering once and going silent.
• AI Insights in Flight Status We added an AI interpretation layer to Flight Status that gives you a cleaner read on what is happening during IROPS, without having to parse through raw delay commentary.
• Multi-Alert Creation (Limited Rollout) Some of you will start seeing a "Create Multiple Alerts" widget in Awards and Upgrades. We are rolling this out gradually, so access is not universal yet. If you have it, let us know what you think.

New Seat Map Experience (Beta) We are building a new seat map experience and want members of this thread involved early. PM us your ExpertFlyer account email and we will send setup instructions.

We have a member of our team looking into this. We'll post an update here once we know more.

update: I called JAL, and many of the window seats marked occupied are in fact blocked.

It may be unrelated (and may not even be an ExpertFlyer issue) but I had a possibly similar experience on a Qantas flight this week. This is a screenshot of the seat map taken after we pushbacked:


5B (and 5A and 5C) was occupied. 5D (and 5E) was not..

False and No Notifications for HA/SA
 

Got a false notification yesterday:This is a notification that your Flight Schedule Alert "SEA to YYJ Alert" has detected a change in the flight schedule.

• For: AS2048
• From: SEA to YYJ
• Departing: 06/25/26 09:50
• Arriving: 06/25/26 10:44

New Flight Schedule:

• For: AS2048
• From: SEA to YYJ
• Departing: 06/25/26 09:50
• Arriving: 06/25/26 10:44

Went to HA site. No change on parameters, just like above. So, why the notification?

I then looked at EF for the following: scheduled notificatoin

HNL to SEA AS142Depart 06/24/26 9:20 PM

Arrive 06/25/26 6:00 AM

Actual HA/AS schedule has changed to:
No notification received. Currently scheduled for Departing at 11:20 PM and arriving at 8;00 AM. Went to EF site and resubmitted querry, and same false information given

ExpertFlyer Voice , what is going on?

Is EF fare flight availability currently down?

All AI tools hallucinate and should not be trusted, but ExpertFlyer's new AI flight status summary is maybe one of the worst I've seen! Beware, and shame on ExpertFlyer for releasing something so obviously unusable?

"The flight departed at 1:32pm, 6 minutes later than the scheduled time of 1:20pm", when it actually departed 6 minutes earlier at 1:14pm, and also, 1:32pm is not 6 minutes after 1:20pm even if that is what happened!

The flight did not land at 3:49pm (that time is nowhere in the source data, the AI just made it up!). It was also never scheduled to arrive at 3:43pm!

Sending you a PM for more info.

Fair points. The AI misread the GDS on the departure time and scheduled arrival. That's on us. The feature is in beta and focused on translating delay and cancellation reasons into plain language. The raw GDS message is always shown alongside it. We're looking into ways to make it more reliable.

Seat maps not working. All I get is...

https://cimg7.ibsrv.net/gimg/www.fly...67675b5812.png

LH345 Departure date March 5 2026 does not show up in Expertflyer Flight Details / Flight Status at all.
United app does, for instance, show this flight and so does Lufthansa's website.

ExpertFlyer Voice : No response from you on this query. No live for JL?
