Do not use them. It's a scam. Terrible service. I booked a flight 4 month's in advance with mytrip.com and Philippine airlines. I used mytrip.com as they were the cheapest. Then got an email within a day of booking to say that the airline had made a scheduled change and moved the first leg of the trip to the exact same time as the second leg of my trip. The airline said it's free to reissue me a ticket, but they mytrip.com charged me £40. I had to pay it as the only free option they gave me, made it impossible to make my trip. I paid, picked my dates and it took over 6 weeks for them to confirm my changes. In that time I lost deposits on hotels as I couldn't confirm my arrival dates etc. I called them twice a week and even called the airline multiple times to check the dates were still free. The airline said it would have taken 2 mins and 1 email to change my dates. Mytrip.com kept telling me it was a long process. They had to refer my case to the booking department, until finally I spoke to one person who was willing to help and he rebooked my tickets in mins while I was on the phone.
