Gary Smith and Fleming Greyson have been v helpful on separate occasions. Haven't flown yet so still tbc on that front. Have had a few ups and downs with this booking to say the least. Customer service in terms of speaking with staff has been positive on the whole, but general experience hasn't been the best. Had a mishap with booking the wrong return date originally (thought this was 100% my mistake however on reading other reviews I'm wondering whether this is a more common occurrence...). Despite noticing immediately and wanting to change these flights and transfer the money paid onto the correct ones plus pay any excess, I was told I had to incur a cost to cancel even though I was planning on rebooking instantly through TravelUp. I was v upset by the amount I was being charged and the rush I was in to authorise (about 15mins allowed), but I then spoke to someone called Gary the following day who was very helpful, rang me very quickly and did all he could to help reduce the charge a bit. Very much appreciated. Both of the flights I carefully selected at the time of booking have since been changed. Time change for one is not ideal but the other works out ok for us, the principal frustrated me though. Customer service today discussing this has been nice enough and shown efforts to try and help. Have spoken to Fleming Greyson via email and he has been very helpful. Appreciate that not all of the above has been within travelup's control or responsibility. The only thing holding this back from an extra star is the lack of further compensation for the hassle of all of these changes, especially in light of the lack of flexibility with changing my flights at the start of the process. My issues today have been satisfactorily resolved though and I am content with the level and speed of response from Fleming. Thank you to both Fleming and Gary!
