There is an issue with fares listing when there are many fares. I think it could be the issue with how GDS response is converted into text which is displayed rather than a GDS glitch.
For example, I search fares from NYC to MOW on any airline with 19 June and 29 June outbound and inbound respectively.
It is clear that the list of fares breaks somehow between AZ economy fare VHWB67US (USD1061) and OS business fare DRC14E (USD 6676). If I filter business only I only get one business fare before the above OS fare which is current AY sale fare (ICAMPUS, USD 891). So tons of fares are lost.
These are only shown when specific airlines search is done, which is not very convenient and promises that I can miss good deals
I have sent the same to the e-mail, thanks!
