Never never an e-ticket internationally, esp to a 3rd World country. We had a disaster in Egypt with an e-ticket that TWA insisted on selling us in SFO. Flew in from Jordan to Cairo and we were not allowed in the transit lounge! No ticket. The customs and immigration guys never heard of an e-ticket, regarded it as a receipt. Had to exit the airport secure area, buy a visa for $30 and return. Was lucky even to get in since Egypt requires an on-going or return ticket for entry to the country!
