I will never book with them again . It is absolutely a scam, My son had warned me about scam claims vs this company . However, I remember I used this online agent a long time ago, and my last booking with them was ok. The booking page would trick you into paying for all the extra insurance without showing the real cost of all items which they automatically add to your invoice, a few small prices items show,, I was very careful , reading every add on items , I did not check any boxes, except remember I click only 1 item that show trip cancellation which cost less than $3.00, I skip all other add on lines and didn't realized, if you ignore the add on they will automatically add them to your invoice, there is no final invoice Total price show before I click continue book, once I click the continue booking, there is no way back, by the time I see my invoice it has added $100 more insurance cost , unable to go back to fix. Call them right away, a lady on the line told us that there is nothing they can do. If I cancel the booking they charge me $200, then hangup, I was so upset, any online business will let you correct error within an hour or day. She claimed that I saw the extra charges and agree to book, but I did not see the addition cost at all, I did not see the grand total cost before I click booking. If they show me the total price before I click book I will decline and cancel the booking. Finally we call the insurance company that Flightnetwork charged me the extra $100 insurance policy which they claim I purchased the insurance, but I did not aware or agreed to buy .
The insurance company was very helpful, the insurance operator help us connected to Flight network and help us sort out the dispute, I finally got my $100 insurance charge cancelled. This is a very bad experiences, their price is the lowest I can find for the same ticket , but I will never going back again. My family call me stupid , I thought I can save about $17 compare to other , but no, my credit card charge more than the price which I book . I will never use this online travel again
