whenever i fly EK, i always ask for upgrade. in fact i got upgraded to business class once when flying back to dubai from milan. i am a blue skywards holder. i see nothing wrong in asking to be upgraded and getting one for free

..... i agree that it is EK's decision to reject or accept a request.
i think the better attitude is to be happy for others who are able get something better to enjoy especially to those who could not afford such luxury. i bet you that they will have the same smile and enjoyment as i did when i got one.
