I booked Finnair flights through TravelUp but when I came to check-in I found that the time of the return flight had changed. I phoned Travel Up but they told me that it wasn't changed on their system & that I needed to contact Finnair. Finnair were useless & said I needed to contact American Airlines who were running the flight. American Airlines were very helpful & they confirmed that the flight time had been changed BUT they couldn't re-iisue my e-ticket - it had to be done by the booking agent, TravelUp. So again I phoned Travel Up who continued to deny that it had been changed & I eventually insisted that I talk to someone more senior in their organisation. He did actually listen to what I told him & eventually he contacted American Airlines who confirmed the flight time change with him. TravelUp promised to re-issue the e-ticket but despite 3 emails to them while I was travelling I did not receive it from them & had to sort it out myself at the airport. Their service was truly lousy, just passing the buck, leading to a lot of time & frustration for me in getting this sorted
