When I booked flight to Toronto my friend happened to accompany me, so we booked seats simulteniusly. It appeared that I payed $17 more than him for no reason. Later on I saw on reddit that booking companies might increase ticket price if you are using an apple device because their marketing department think that apple owners wealthy people and they can charge more from them. Be aware!
Their promptness for any type of papers – even if they are urgent and/or difficult – is simply impressive. Thanks for such quality! It would be better if you charged less but anyway service is outstanding.
