The biggest disadvantage of Saver fares is that once purchased, you money flies, whether or not you accompany it. No refunds, sans IRROPS & schedule changes > 60 mins & no wallet credit for future use. Also, Same Day changes are not permitted.

A Main fare purchase would allow you to select seats in the Elite & oneworld section which includes the exit rows. Row 16 does not recline but Row 17 does, they have extra legroom, exceeding Premium and armrests are not fixed. You have flexibility to change your flight (fare difference will apply) and cancel the tickets with the funds going to your wallet; good for one year from cancellation, not from purchase. Those funds are lumped together and are not attributed individually to each pax in the PNR. Wallet funds can be used to purchase a ticket for anyone so while you may not have opportunity to use the funds, you can use them for friends or family. I look at the fare difference from Saver to Main to be an insurance policy to protect my $$ and relieve the restrictions they impose.
